in less than two hours at a cost of more than a thousand dead and some 5,000 wounded. Sharon would later recall that what Schneerson had told him was a tragedy, "but unfortunately, that happened." Early political career, 1974–2001 Beginnings of political career In the 1940s and 1950s, Sharon seemed to be personally devoted to the ideals of Mapai, the predecessor of the modern Labor Party. However, after retiring from military service, he joined the Liberal Party and was instrumental in establishing Likud in July 1973 by a merger of Herut, the Liberal Party and independent elements. Sharon became chairman of the campaign staff for that year's elections, which were scheduled for November. Two and a half weeks after the start of the election campaign, the Yom Kippur War erupted and Sharon was called back to reserve service. On the heels of being hailed as a war hero for crossing the Suez in the 1973 war, Sharon won a seat to the Knesset in the elections that year, but resigned a year later. From June 1975 to March 1976, Sharon was a special aide to Prime Minister Yitzhak Rabin. He planned his return to politics for the 1977 elections; first, he tried to return to the Likud and replace Menachem Begin at the head of the party. He suggested to Simha Erlich, who headed the Liberal Party bloc in the Likud, that he was more able than Begin to win an election victory; he was rejected, however. He then tried to join the Labor Party and the centrist Democratic Movement for Change, but was rejected by those parties too. Only then did he form his own list, Shlomtzion, which won two Knesset seats in the subsequent elections. Immediately after the elections, he merged Shlomtzion with the Likud and became Minister of Agriculture. When Sharon joined Begin's government, he had relatively little political experience. During this period, Sharon supported the Gush Emunim settlements movement and was viewed as the patron of the settlers' movement. He used his position to encourage the establishment of a network of Israeli settlements in the occupied territories to prevent the possibility of Palestinian Arabs' return to these territories. Sharon doubled the number of Jewish settlements on the West Bank and Gaza Strip during his tenure. After the 1981 elections, Begin rewarded Sharon for his important contribution to Likud's narrow win, by appointing him Minister of Defense.
