Treaty of Almizra

According to the treaty, all lands south of a line from Biar to Villajoyosa through Busot were reserved for Castile.

The clause by which neither party seemed capable of residing was that neither crown should diminish the partition assigned to the other or put any obstacle in the way of the other attaining unto his portion.

That clause was broken when James I conquered Caudete, Villena, and Sax, which technically belonged to Castile.

The treaty was signed in Campo de Mirra, where a monument, erected in 1977, still commemorates it.

In 1296, during a break in the war between the two crowns, James II of Aragon conquered the Kingdom of Murcia.
