Following the three Knesset elections between April 2019 and March 2020, Israeli political parties were eventually able to form a National Unity coalition government led by Likud and the recently formed Blue and White parties, and also including several of their smaller allies. This was not the first time in the history of the Israeli party system that the two largest parties agreed to share power in the grand coalition government. However, this most recent National Unity coalition was unique in terms of the processes leading to its formation, its eventual composition, and its duration in office. The paper argues that the growing personalization of Israeli party politics provides a helpful theoretical and analytical perspective to make sense of the puzzling nature of this government. The first part of the paper provides a comparative historical assessment of the Israel’s National Unity governments since 1949 focusing on the length of time their formation took after the election; the content of the coalition agreements; the partisan composition and the distribution of government portfolios among coalition members; the duration of the government; and the reason for its termination. The second part of the paper shows that Israel’s National Unity governments cannot be consistently explained in terms of conventional theories of grand coalition and surplus majority governments. The third part of the paper shows how the personalization of Israeli politics can help us understand the puzzle of the most recent National Unity government.
