[2002] Zafarullah Khan Jamali Becomes Prime Minister: Mir Zafarullah Khan Jamali was elected the 20th Prime Minister of Pakistan by the newly elected Parliament on November 21, 2002. President General Pervez Musharraf administered the oath to the new Prime Minster at the Aiwan-i-Sadr on November 23. He now heads Pakistan's first civilian government after three years of military rule of General Pervez Musharraf.
In January 2004 Musharraf sought and received an unprecedented vote of confidence from a parliamentary electoral college. In August Shaukat Aziz, a former banker and minister of finance, took the premiership. Musharraf, however, clearly continued to hold the reins of power, and despite repeated promises to return the country to full civilian authority, he announced at the end of the year that the country was too fragile for him to comply with his own deadlines. This applied also to the president’s refusal to step down as head of the armed forces, despite repeated demands by political opponents that he do so. On the other side of the political spectrum, Musharraf had to contend with constant attacks from the MMA, who accused him of seeking to secularize Pakistan. The country continued to be subject to increasing incidents of sectarian violence, including suicide bombings at mosques and other public places. Adding to this human-generated calamity, Pakistan suffered a devastating earthquake in October 2005 in the Kashmir region that killed tens of thousands of people and left hundreds of thousands homeless.

In early 2007 Musharraf began seeking reelection to the presidency. However, because he remained head of the military, opposition parties and then the Pakistan Supreme Court objected on constitutional grounds. In March Musharraf dismissed Chief Justice Iftikhar Mohammad Chaudhry, which sparked a general strike of Pakistani lawyers and outbreaks of violent protest in various parts of the country; the Supreme Court overturned the dismissal in July, and Chaudhry was reinstated. In October an electoral college consisting of the parliament and four provincial legislatures voted to give Musharraf another five-year term, although opposition members refused to participate in the proceedings. After the Supreme Court delayed the pronouncement of this outcome (in order to review its constitutionality), Musharraf declared a state of emergency in early November. The constitution was once again suspended, members of the Supreme Court (including Chaudhry) were dismissed, and the activities of independent news media organizations were curtailed. Later in the month, the Supreme Court, reconstituted with Musharraf appointees, upheld his reelection; Musharraf subsequently resigned his military commission and was sworn into the presidency as a civilian.

In the fall of 2007 Nawaz Sharif and Benazir Bhutto—who had also been living in exile—were permitted to return to Pakistan, and each began campaigning for upcoming parliamentary elections scheduled for early January 2008. At the end of December, however, Bhutto was assassinated at a political rally in Rawalpindi, an act that stunned Pakistanis and set off riots and rampages in different parts of the country. Musharraf, having only just lifted the state of emergency, had to again place the armed forces on special alert, and he was forced to postpone the election until mid-February.

The outcome of the voting was seen as a rejection of Musharraf and his rule; his PML-Q party finished a distant third behind the PPP (now led by Asif Ali Zardari, Bhutto’s widower), which captured about one-third of the parliamentary seats up for election, and Sharif’s party, the PML-N, with about one-fourth of the seats. In March the PPP and PML-N formed a coalition government. Yousaf Raza Gilani, a prominent member of the PPP and a former National Assembly speaker, was elected prime minister.

Disagreements emerged within the governing coalition in the months following its formation, particularly regarding the reinstatement of the Supreme Court judges Musharraf had dismissed late the previous year, and these disputes threatened to destabilize the alliance. Nevertheless, in August 2008 the coalition moved to begin impeachment charges against Musharraf, citing grave constitutional violations; on August 18, faced with the impending proceedings, Musharraf resigned.

Pakistan under Zardari
Conflict within the coalition continued to escalate following Musharraf’s departure. In light of ongoing differences, including disputes over Musharraf’s successor, Sharif subsequently withdrew the PML-N from the governing coalition and indicated that his party would put forth its own candidate in the presidential elections announced for early September; however, neither the PML-N nor the PML-Q candidate won enough support to pose a challenge to Zardari, the PPP’s candidate, and on Sept. 6, 2008, he was elected president.

Friction between Zardari and Sharif intensified in early 2009 when the Supreme Court voted to disqualify Sharif’s brother from his position as chief minister of the Punjab and to uphold a ban prohibiting Sharif himself from holding political office (the ban stemmed from his 2000 conviction for high crimes). Sharif alleged that the court’s rulings were politically motivated and backed by Zardari. In addition, the status of the Supreme Court judges dismissed under Musharraf who had yet to be reinstated—one of the issues that had undermined the Sharif-Zardari coalition—remained a major source of conflict between the two rivals. In March 2009 Sharif broke free of an attempt to place him under house arrest and headed toward the capital, where he planned to hold a rally advocating for the reinstatement of the judges. Faced with this prospect, the government agreed to reinstate Chief Justice Chaudhry and a number of other Supreme Court judges who had not yet been returned to their posts. The move was seen as a political victory for Sharif and a significant concession on the part of Zardari, who is thought to have opposed Chaudhry’s return because of the possibility that the amnesty Zardari had received under Musharraf might be overturned. Shortly thereafter, Sharif’s brother was also returned to his position.

In October 2008 limited trade between the Pakistani- and Indian-administered portions of Kashmir resumed. It was the first such commerce in more than 60 years and signaled improved relations between the two countries.
