League football began in Israel in 1949–50, a year after independence. However, the financial and security crises gripping the young nation caused the 1950–51 season to be abandoned before it had started. When football resumed in 1951–52, the new top division went by the name of Liga Alef. The 1952–53 season was also not played, and Liga Alef resumed in 1953–54.
In the 1955–56 season, Liga Leumit came into existence as the new top division, with Liga Alef becoming the second division. In the summer of 1976, restructuring saw the creation of Liga Artzit as a new second tier, and the second demotion of Liga Alef, as it became the third division. Further restructuring to create the Israeli Premier League in the summer of 1999 saw Liga Alef demoted again, this time to the fourth tier. At the end of the 2008–09 season, Liga Artzit was scrapped as the Premier League and Liga Leumit were expanded to 16 clubs each, with Liga Alef becoming the third tier once more.
Today, Liga Alef is split into two regional divisions on a north-south basis. Because Israel's northern half is much more densely populated than the desert south, the dividing line between the northern and southern divisions is somewhere between Haifa and Tel Aviv, meaning that the southern "half" covers about three-quarters of the country. Although this inequality is partially offset by the fact that there are so few clubs south of Beersheba (Dimona, Yeroham, Mitzpe Ramon and Eilat are the only sizable towns south of the city), the northern clubs tend to be clustered in the Galilee region, making travel to away matches much less of a chore.
Each division has sixteen clubs, who play each other home and away to make a 30-game season. The club finishing top of each regional division is promoted to Liga Leumit, whilst the eight second to fifth placed clubs have a play-off, with the winner playing-off against the third-bottom club in Liga Leumit for a place in that division. The bottom two from each division are relegated to Liga Bet, the fourth tier, and the two third-bottom clubs playing-off against play-off winners from Liga Bet for a place in Liga Alef. Coming into Liga Alef are the two or three clubs relegated from Liga Leumit and the four to six clubs promoted from Liga Bet (the winner of each of the four regional divisions, and one or two more runners-up, had they are successful in the play-off). The clubs are then pooled and assigned to the most geographically appropriate of the two divisions.
The following clubs are participating in the 2019–20 season:
1 No clubs were relegated as the league was expanded to 14 clubs in the following season.
4 No clubs were promoted or relegated after the Israel Football Association decided to abandon the league before the end of the season, due to suspicions of bribery.
1 There was no automatic promotion in the 1973-74 season. Hapoel Acre finished fifth in the promotion play-offs and remained in Liga Alef. However, runners-up, Shimshon Tel-Aviv, finished second in the promotion play-offs and were promoted to Liga Leumit.
2 Hapoel Kiryat Shmona and Hapoel Safed were reprieved from relegation after the Israel Football Association decided to expand Liga Leumit to 18 clubs and Liga Alef to 17 clubs in each division for the following season.
9 There was no automatic promotion in the 1986-87 season. Maccabi Hadera finished third in the promotion play-offs after Hapoel Bat Yam of Liga Alef South and Hapoel Ramat Gan of Liga Artzit and remained in Liga Alef.
