Bangladesh Governments: (1971-2009)
Bangladesh’s first government took oath on April 10, 1971. The provisional government of the new nation of Bangladesh was formed in Dhaka with the president of the republic, justice Abu Sayed Choudhury and Taj Uddin as Prime Minister.

Sheikh Mujibur Rahman, 1972–75:
The first parliamentary elections held under the 1972 constitution were in March 1973, with the Awami League winning a massive majority. No other political party in Bangladesh's early years was able to duplicate or challenge the League's broad-based appeal, membership, or organizational strength. Mujib and his cabinet having no experience in governance nor administration, relied heavily on experienced civil servants and political factions of the Awami League, the new Bangladesh Government focused on relief, rehabilitation, and reconstruction of the economy and society. Mujib nationalised the entire economy, banking and industrial sector. Economic conditions took a serious downturn. On top of that heavy corruption among his own party members, factions and senior leadership also added to the devastation and famine. The then U.S. Secretary of State termed Bangladesh a Bottomless Basket. In December 1974, Mujib decided that continuing economic deterioration and mounting civil disorder required strong measures. After proclaiming a state of emergency, Mujib used his parliamentary majority to win a constitutional amendment limiting the powers of the legislative and judicial branches, establishing an executive presidency, and instituting a one-party system, the Bangladesh Krishak Sramik Awami League (BAKSAL), which all members of Parliament were obliged to join.
Despite promises, no sign of improvement in the economic situation surfaced. Implementation of promised political reforms was almost nil, and criticism of government policies became increasingly centered on Mujib. Serious disorientation in the armed services, disenchantment in society, detoriaration of law and order created a huge mistrust of Mujib and his government including the Awami League itself. The then chief of army staff K M Shafiullah and chief of air staff A.K. Khandker stood stunned and idle during this situation. In August 1975, Mujib, and most of his family, were assassinated by a small group of mid-level army officers. Mujib's daughters, Sheikh Hasina and Sheikh Rehana, happened to be out of the country. A new government, headed by former Mujib associate Khandakar Moshtaque, was formed.
1975 August-1975 November:
Mujib's senior cabinet minister Khondakar Mushtaq Ahmad formed a new government and immediately initiated a few critical changes in Mujib's policies and rules of business in government. However, within three months the first military coup took place in Bangladesh by senior members of the army, removing Mushtaq and replacing his administration. Armed forces personnel along with internal political and government forces fell into a chaotic dispute, resulting in a vacuum at the highest level of government.
Ziaur Rahman, 1975–81:
Following Mushtaq's removal, jail killings of arrested members Mushtaq's cabinet, and assassination of Brigadier General Khaled Musharaf by a segment of army personnel, a very short lived revolution resulted in the emergence of arrested deputy Army Chief of Staff Major General Ziaur Rahman, who managed to take the lead and bring the whole nation out of a political quagmire. His first action was to communicate to the people through radio and television and bring order and calm to the nation. He pledged full support to the civilian government headed by President Chief Justice Sayem. Acting at Zia's behest, Sayem dissolved Parliament, and instituted state of emergency under martial law. Fresh elections were to be in 1977 under a multi party democracy with full freedom of the press.
As President, Zia announced a 19-point program of economic reform and began dismantling the MLA. Keeping his promise to hold elections, Zia won a 5-year term in June 1978 elections, with 76% of the vote. In November 1978, his government removed the remaining restrictions on political party activities in time for parliamentary elections in February 1979. These elections, which were contested by more than 30 parties, marked the culmination of Zia's transformation of Bangladesh's Government from the MLA to a democratically elected, constitutional one. The AL and the Bangladesh Nationalist Party (BNP), founded by Zia, emerged as the two major parties. The constitution was again amended to provide for an executive prime minister appointed by the president, and responsible to a parliamentary majority. Zia invigorated a strong foreign policy based on sovereignty and economic independence. He initiated many social programs to uplift the poor through honest hard work and education. His greatest legacy on the people of Bangladesh was unity and self-dependence.
In May 1981, Zia was assassinated in Chittagong by dissident elements of the military. There was no coup or uprising attempted and the major conspirators were ever taken into custody or killed. Vice President Justice Abdus Sattar was sworn in as acting president, and elected president as the BNP's candidate six months later. Sattar followed the policies of his predecessor and retained essentially the same cabinet.
Hussain Mohammed Ershad, 1982–90:
Army Chief of Staff Lt. Gen. Hussain Mohammed Ershad assumed power in the second, but, bloodless coup in March 24, 1982. To strenghthen his hold on government Ershad suspended the constitution and—citing pervasive corruption, ineffectual government, and economic mismanagement—declared martial law. The following year, Ershad assumed the presidency, retaining his positions as army chief and CMLA, first time in Bangladesh. During most of 1984, Ershad sought the opposition parties' participation in local elections under martial law. The opposition's refusal to participate, however, forced Ershad to abandon these plans. Ershad sought public support for his regime in a national referendum on his leadership in March 1985. He won overwhelmingly, although turnout was small. Two months later, Ershad held elections for local council chairmen. Pro-government candidates won a majority of the posts, setting in motion the President's ambitious decentralization program. Political life was further liberalized in early 1986, and additional political rights, including the right to hold large public rallies, were restored. At the same time, the Jatiya Party, designed as Ershad's political vehicle for the transition from martial law, was established.
Despite a boycott by the BNP, led by President Zia's widow, Begum Khaleda Zia, parliamentary elections were held on schedule in May 1986. The Jatiya Party won a modest majority of the 300 elected seats in the national assembly. The participation of the Awami League led by the late Prime Minister Mujib's daughter, Sheikh Hasina Waze -lent the elections some credibility, despite widespread charges of voting irregularities.
Ershad resigned as Army Chief of Staff and retired from military service in preparation for the presidential elections, scheduled for October. Protesting that martial law was still in effect, both the BNP and the AL refused to put up opposing candidates. Ershad easily outdistanced the remaining candidates, taking 84% of the vote. Although Ershad's government claimed a turnout of more than 50%, opposition leaders, and much of the foreign press, estimated a far lower percentage and alleged voting irregularities.
Ershad continued his stated commitment to lift martial law. In November 1986, his government mustered the necessary two-thirds majority in the national assembly to amend the constitution and confirm the previous actions of the martial law regime. The President then lifted martial law, and the opposition parties took their elected seats in the national assembly.
In July 1987, however, after the government hastily pushed through a controversial legislative bill to include military representation on local administrative councils, the opposition walked out of Parliament. Passage of the bill helped spark an opposition movement that quickly gathered momentum, uniting Bangladesh's opposition parties for the first time. The government began to arrest scores of opposition activists under the country's Special Powers Act of 1974. Despite these arrests, opposition parties continued to organize protest marches and nationwide strikes. After declaring a state of emergency, Ershad dissolved Parliament and scheduled fresh elections for March 1988.All major opposition parties refused government overtures to participate in these polls, maintaining that the government was incapable of holding free and fair elections. Despite the opposition boycott, the government proceeded. The ruling Jatiya Party won 251 of the 300 seats. The Parliament, while still regarded by the opposition as an illegitimate body, held its sessions as scheduled, and passed a large number of bills, including, in June 1988, a controversial constitutional amendment making Islam Bangladesh's state religion. By 1989, the domestic political situation in the country seemed to have quieted. The local council elections were generally considered by international observers to have been less violent and more free and fair than previous elections. However, opposition to Ershad's rule began to regain momentum, escalating by the end of 1990 in frequent general strikes, increased campus protests, public rallies, and a general disintegration of law and order.
On December 6, 1990, Ershad offered his resignation. On February 27, 1991, after 2 months of widespread civil unrest, an interim government oversaw what most observers believed to be the nation's most free and fair elections to date.

Khaleda Zia, 1991–96:
The center-right BNP won a plurality of seats and formed a coalition government with the Islamic party Jamaat-e-Islami Bangladesh, with Khaleda Zia, obtaining the post of Prime Minister. Only four parties had more than 10 members elected to the 1991 Parliament: The BNP, led by Prime Minister Begum Khaleda Zia; the AL, led by Sheikh Hasina; the Jamaat-e-Islami, led by Golam Azam; and the Jatiya Party, led by acting chairman Mizanur Rahman Choudhury while its founder, former President Ershad, served out a prison sentence on corruption charges. The electorate approved still more changes to the constitution, formally re-creating a parliamentary system and returning governing power to the office of the prime minister, as in Bangladesh's original 1972 constitution. In October 1991, members of Parliament elected a new head of state, President Abdur Rahman Biswas.
In March 1994, controversy over a parliamentary by-election, which the opposition claimed the government had rigged, led to an indefinite boycott of Parliament by the entire opposition. The opposition also began a program of repeated general strikes to press its demand that Khaleda Zia's government resign and a caretaker government supervise a general election. Efforts to mediate the dispute, under the auspices of the Commonwealth Secretariat, failed. After another attempt at a negotiated settlement failed narrowly in late December 1994, the opposition resigned en masse from Parliament. The opposition then continued a campaign of Marches, demonstrations, and strikes in an effort to force the government to resign. The opposition, including the Awami League's Sheikh Hasina, pledged to boycott national elections scheduled for February 15, 1996.
In February, Khaleda Zia was re-elected for the second term by a landslide in voting boycotted and denounced as unfair by the three main opposition parties. In March 1996, following escalating political turmoil, the sitting Parliament enacted a constitutional amendment to allow a neutral caretaker government to assume power conduct new parliamentary elections; former Chief Justice Mohammed Habibur Rahman was named Chief Advisor (a position equivalent to prime minister) in the interim government. New parliamentary elections were held in June 1996 and were won by the Awami League; party leader Sheikh Hasina became Prime Minister.

Sheikh Hasina, 1996–2001:
Sheikh Hasina formed what she called a "Government of National Consensus" in June 1996, which included one minister from the Jatiya Party and another from the Jatiyo Samajtantric Dal, a very small leftist party. The Jatiya Party never entered into a formal coalition arrangement, and party president H.M. Ershad withdrew his support from the government in September 1997. Only three parties had more than 10 members elected to the 1996 Parliament: The Awami League, BNP, and Jatiya Party. Jatiya Party president, Ershad, was released from prison on bail in January 1997.
Although international and domestic election observers found the June 1996 election free and fair, the BNP protested alleged vote rigging by the Awami League. Ultimately, however, the BNP party decided to join the new Parliament. The BNP soon charged that police and Awami League activists were engaged in large-scale harassment and jailing of opposition activists. At the end of 1996, the BNP staged a parliamentary walkout over this and other grievances but returned in January 1997 under a four-point agreement with the ruling party. The BNP asserted that this agreement was never implemented and later staged another walkout in August 1997. The BNP returned to Parliament under another agreement in March 1998.
In June 1999, the BNP and other opposition parties again began to abstain from attending Parliament. Opposition parties have staged an increasing number of nationwide general strikes, rising from 6 days of general strikes in 1997 to 27 days in 1999. A four-party opposition alliance formed at the beginning of 1999 announced that it would boycott parliamentary by-elections and local government elections unless the government took steps demanded by the opposition to ensure electoral fairness. The government did not take these steps, and the opposition has subsequently boycotted all elections, including municipal council elections in February 1999, several parliamentary by-elections, and the Chittagong city corporation elections in January 2000. The opposition demands that the Awami League government step down immediately to make way for a caretaker government to preside over parliamentary and local government.
Four Party Alliance led by BNP, 2001–2006:
The four-party alliance led by the Bangladesh Nationalist Party (BNP) won over a two-thirds majority in Parliament. Begum Khaleda Zia was sworn in on October 10, 2001, as Prime Minister for the third time.
In July 2006, the Awami League government stepped down to allow a caretaker government to preside over parliamentary elections. In August, Khaleda Zia and Sheikh Hasina agreed to respect the results of the election, join Parliament win or lose, forswear the use of hartals (violently enforced strikes) as political tools, and if successful in forming a government allow for a more meaningful role for the opposition in Parliament. The caretaker government was successful in containing the violence.
Caretaker Government, Oct. 2006–Jan. 2009:
On January 12, 2007, former Bangladesh Bank governor Fakhruddin Ahmed was sworn in as the new Chief Adviser, and ten new advisers (ministers) were appointed. The government announced elections would occur in late 2008. As of November 19, 2008, elections were scheduled for December 8, 2008.
Sheikh Hasina, January 2009–present:
On 19 November 2008 Awami League & Jatiya Party agreed to contest the elections jointly under the Caretaker Government to be held on 29 December 2008. Out of the 300 Constituencies in the Parliament, Ershad's Jatiya Party will contest from 49 seats and Awami League and members of a leftist wing Fourteen Party Coalition from the rest 250 seats. Thus the Grand Alliance emerged in Bangladesh; known as Mohajote.
On Dec 29, 2008 Sheikh Hasina became Prime Minister and formed the government and a cabinet which included ministers from Jatiya Party although any post for Hussain Mohammed Ershad, is yet to be decided as the earlier agreed Presidency seems elusive.
