After Prime Minister Shamir lost a Knesset vote of confidence early in 1984, new elections in July provided no clear winner, with both Labor and Likud considerably short of a Knesset majority and unable to form even narrow coalitions. After several weeks of difficult negotiations, they agreed on a government of national unity, including the rotation of the office of Prime Minister and the combined office of Vice Prime Minister and Foreign Minister midway through the government's 50-month term.

During the first 25 months of unity government rule, Labor's Shimon Peres served as Prime Minister, while Likud's Shamir held the posts of Vice Prime Minister and Foreign Minister, until they switched positions in October 1986. In November 1988 elections, Likud edged Labor out by one seat but was unable to form a coalition, producing another national unity government in January 1989. Yitzhak Shamir became Prime Minister, and Shimon Peres became Vice Prime Minister and Finance Minister. This government fell in March 1990, however, in a vote of no confidence precipitated by disagreement over the government's response to U.S. Secretary of State Baker's initiative in the peace process. Labor Party leader Peres was unable to attract sufficient support among the religious parties to form a government. Yitzhak Shamir then formed a Likud-led coalition government, including members from religious and right-wing parties.

Shamir's government took office in June 1990, and held power for 2 years. In the June 1992 national elections, the Labor Party reversed its electoral fortunes, taking 44 seats. Labor Party leader Yitzhak Rabin formed a coalition with Meretz (a group of three leftist parties) and Shas (an ultra-Orthodox religious party). The coalition included the support of two Arab-majority parties. Rabin became Prime Minister in July 1992, presiding over the signing of the Oslo accords with the Palestine Liberation Organization. However, Rabin was assassinated by a right-wing Jewish radical on November 4, 1995. Peres, then Deputy Prime Minister and Foreign Minister, once again became Prime Minister and immediately proceeded to carry forward the peace policies of the Rabin government and to implement Israel's Oslo commitments, including military redeployment in the West Bank and the holding of historic Palestinian elections on January 20, 1996.

Enjoying broad public support and anxious to secure his own mandate, Peres called for early elections after just 3 months in office. (They would have otherwise been held by the end of October 1996.) In late February and early March, a series of suicide bombing attacks by Palestinian terrorists took some 60 Israeli lives, seriously eroding public support for Peres and raising concerns about the peace process. Increased fighting in southern Lebanon, which also brought Katyusha rocket attacks against northern Israel, also raised tensions and weakened the government politically a month before the May 29 elections.

In those elections--the first and only direct election of a Prime Minister in Israeli history--Likud leader Binyamin Netanyahu won by a narrow margin, having sharply criticized the government's peace policies for failing to protect Israeli security. Netanyahu subsequently formed a right-wing coalition government publicly committed to pursuing the peace process, but with an emphasis on security and reciprocity. In 1999, with a shrunken coalition and facing increasing difficulty passing legislation and defeating no-confidence motions, Netanyahu dissolved parliament and called for new elections. This time, the Labor candidate--Ehud Barak--was victorious. Barak formed a mixed coalition government of secular and religious parties, with Likud in the opposition. In May 2000, Barak fulfilled one of his major campaign promises by withdrawing Israeli forces from Southern Lebanon. However, by mid-autumn, with the breakdown of the Camp David talks and the worsening security situation caused by the new intifada, Barak's coalition was in jeopardy. In December, he resigned as Prime Minister, precipitating a new prime ministerial election.

In a special election on February 6, 2001, after a campaign stressing security and the maintenance of Israeli sovereignty over Jerusalem, Likud leader Ariel Sharon defeated Barak by over 20 percentage points. As he had promised in his campaign, Sharon formed a broad unity government that included the Labor and Likud parties, the far-right parties, some smaller secular parties, and several religious parties. The unity government collapsed in late 2002, and new elections were held in January 2003. Sharon again won, and formed a new government consisting of his own Likud party, the right-wing National Religious Party and National Union party, and centrist Shinui.

The summer of 2004 saw renewed instability in the government, as disagreement over the Gaza disengagement plan resulted in Sharonís firing two ministers of the National Union Party and accepting the resignation of a third from the National Religious Party in order to secure cabinet approval of the plan (it was endorsed on June 6, 2004). Continuing divisions within the Likud on next steps then prompted Ariel Sharon to leave the party in November 2005 to form the Kadima ("Forward") party and call new elections for March 2006. However, Sharon was unexpectedly incapacitated in January 2006 due to a severe stroke and leadership of Kadima shifted to Acting Prime Minister Ehud Olmert, who on March 28 led the party to 29 seats in the Knesset. Labor came in second with 19 seats, and Shas and Likud tied with 12. After intensive coalition negotiations, a new, Kadima-led government, with Labor as "senior partner", was sworn in on May 4, 2006.
