The war ended in the summer of 1949 in an Israeli victory in most sectors. The Israel Defense Forces (lDF), that was established two and a half weeks after the founding of the State, soon became a large, strong army. The Arab states co-signed ceasefire agreements. Large numbers of Jewish immigrants began pouring into Israel while battles were still raging, and by the end of 1949 one million Jews were living in Israel - a figure that couldn't have been envisaged ten or fifteen years earlier.
