İlkadım is a part of the Samsun Metropolitan Municipality. In 1994 it was declared a municipality within the city borders of the Samsun Metropolitan Municipality. With a law in 2008, it became one of the 4 central districts of Samsun by including the lower level municipalities of Gazi and Yeşilkent. At the 2013 Turkish local government reorganisation, the rural part of the district was integrated into the municipality, the villages becoming neighbourhoods.

Currently, it is the largest and most developed district of Samsun and the Black Sea Region in terms of population. With the growth of the region, commercial activities in the center have declined and much of the middle class of Samsun has moved to newer and more modern neighborhoods. Efforts have been made to revitalize İlkadım like the construction of the Sheraton Hotel Samsun, Piazza Samsun and the reconstruction of Samsun Saathane Square and Republic Square (Samsun). The district is also served by extensive public transit including the Samsun Tram.

The district was named İlkadım because Atatürk came to Samsun and took the first step towards independence here on May 19, 1919.
