History
Since the 11th century, Gresik has become an international trade center visited by many nations such as, Chinese, Arabs, Champa, and Gujarat. Gresik Regency is also the first entry point for Islam in Java, which among others is marked by the existence of ancient Islamic tombs from Sheikh Maulana Malik Ibrahim and Fatimah bint Maimun. Gresik has become one of the main ports and trade cities that are quite important since the 14th century, as well as being a haven for ships from Maluku to Sumatra and mainland Asia. This continued until the VOC era. The port of Gresik-Djaratan has functioned as an important commercial center since the eleventh century, trading with merchants from as far away as China, India, and Arabia. Some of these traders helped spread Islam in the area. In 1487 Sunan Giri, also known as Sultan Ainul Yaqin, began to rule Gresik. In his 1515 book, Suma Oriental, the Portuguese apothecary and traveller Tomé Pires described Gresik as "the jewel of Java in trading ports". Sunan Giri's descendants ruled the area for the following two centuries. Initially the Gresik region was part of the Surabaya Regency. In 1974, the Central Government issued PP No. 38 of 1974. All government activities began to be gradually transferred to Gresik and the name changed to Gresik Regency with a center of activity in Gresik town. Also in 1974 the Indonesian government made Gresik, now a suburb of Surabaya, part of Gerbangkertosusila Metropolitan Area, official metropolitan region by Government.
The Gresik Regency was divided at 2010 into eighteen kecamatan, tabulated below with their 2010 Census population.
