Blessed John Sugar and Robert Grissold (d. 1604, linked to 15th-century persecution roots) – Martyred in England for their Catholic faith, part of a broader anti-Catholic persecution that had earlier origins.
Martyrs of Otranto (1480)

After the city fell, about 800 Christian men were executed for refusing to convert to Islam.
Their leader, Antonio Primaldo, was the first to be beheaded.

He was accused of heresy and secretly practicing Judaism (a common accusation during that time).

Beatified for his steadfastness in faith.
Martyrs of Granada (1492)
After the Catholic Monarchs, Ferdinand and Isabella, completed the Reconquista, Muslims and Jews were ordered to convert to Christianity or leave Spain.
Some Christians who were former Muslims (Moriscos) were executed for secretly practicing Islam.
Christian missionaries and converts who defended the faith also suffered persecution.
- Alexios V of Trebizond: Martyred in 1461 after the fall of the Trebizond Empire to the Ottomans for refusing to convert to Islam.
- David of Trebizond: Martyred alongside Alexios V in 1461 for maintaining his Christian faith 1.

These individuals were recognized for their faith and sacrifices during the 15th century, often in the context of religious reform or political conflict. The 15th century saw increasing tensions between Christianity and Islam, especially with the expansion of the Ottoman Empire and the Reconquista in Spain.
