Demak (Javanese: ꦢꦼꦩꦏ꧀) is a regency located in the Indonesian province of Central Java, on the northern coast of the island.

[6] The Sultanate expanded in the expense of the declining Majapahit and its fragments, conquering the coastal region of Tuban around 1527 and reaching inland areas as far as Malang by 1546.

[5] As the capital, the city became an important center for trade and the spread of Islam across the island, and a base of the semi-apocryphal Wali Sanga.

[8] Upon the latter's dissolution on late 1799, administration of the area along with the rest of VOC's territory was transferred to the Dutch Government while Mataram was reduced to several fragmented states in the south coast of Java, including Yogyakarta and Surakarta.

The first five districts listed above are situated in the southwest part of the Regency (and thus adjacent to Semarang City), with an area of 365.99 km2 and 546,254 inhabitants in mid 2023.
