Estêvão Gonçalves Leitão

Estêvão Gonçalves Leitão (c. 1290–1344) was the fourth master of the Order of Christ, elected in 1335 in succession to his brother Martim Gonçalves Leitão, holding office until death. King Afonso IV brought about his election, valuing the military record of his kin.

In the 1336–1339 war with Castile, his men joined the hosts of the bishops of Porto and Braga in routing a Castilian army under Fernando de Castro near Braga in 1337 and killing the commander's brother. He kept the Order's war against the Moors alive as vigorously as his predecessors.
