Upon the death of his father, Selim I, Suleiman entered Constantinople and ascended to the throne as the tenth Ottoman Sultan. An early description of Suleiman, a few weeks following his accession, was provided by the Venetian envoy Bartolomeo Contarini:

The sultan is only twenty-five years [actually 26] old, tall and slender but tough, with a thin and bony face. Facial hair is evident, but only barely. The sultan appears friendly and in good humor. Rumor has it that Suleiman is aptly named, enjoys reading, is knowledgeable and shows good judgment."
