Alice of Champagne was a Queen consort of Cyprus from 1210 to 1218, and regent of Cyprus from 1218 to 1223 and of Jerusalem from 1243 to 1246. She was the eldest daughter of Henry II, Count of Champagne, and Isabella I of Jerusalem. Alice married her stepbrother, Hugh I of Cyprus. She received the County of Jaffa as dowry. After her husbands dead in 1218, she assumed the regency for their infant son, Henry I of Cyprus. Before long, she began to make contacts in her fathers counties in France, because she had a strong claim to Champagne and Brie against her cousin, Theobald IV of Champagne, although the kings of France never acknowledged it.
Alice was the eldest daughter of Isabella I of Jerusalem and her third husband, Henry II, Count of Champagne. She was born around 1193. Her father and Aimery, Lord of Cyprus, agreed that Aimerys eldest surviving son was to marry Henrys eldest surviving daughter, stipulating that she would receive the County of Jaffa as dowry. Henry of Champagne fell from a tower of his palace in Acre and died onSeptember 1197. A month after his death, his widow married Aimery of Lusignan, who had recently been crowned king of Cyprus.
