who invaded constantinople in 1453?\narab muslim armies\nottoman turk armies\nroman catholic armies\neastern…

Brief Explanations:

In 1453, the Ottoman Turks, under Sultan Mehmed II, launched a major military campaign. Constantinople was the capital of the Byzantine Empire. The Ottoman Turks' military strength, use of advanced weaponry (like cannons), and strategic planning led to the fall of the city. This event marked the end of the Byzantine Empire. Arab Muslim armies had earlier expansions but not this specific invasion in 1453. Roman Catholic and Eastern Orthodox armies were more involved in internal Christian - related conflicts (like the East - West Schism related issues) rather than this particular invasion of Constantinople in 1453.

Answer:

Ottoman Turk armies
