This "status quo" was broken by Tumapaqrisiq Kallonna (r. 1511–1546), son of Batara Gowa, who is the first "karaeng" described in detail by the "Gowa Chronicle". Since the days of Batara Gowa, Gowa had had ambitions to annex the affluent port-polity of Garassiq, site of the modern city of Makassar, but it was not until the era of Tumapaqrisiq Kallonna that this was accomplished. Gowa's conquest of Garassiq occurred possibly as early as 1511 and provided the hitherto landlocked polity with much greater access to maritime commerce. Besides Garassiq, the "Gowa Chronicle" credits Tumapaqrisiq Kallonna with conquering, making vassals of, or levying indemnities from thirteen other Makassar states. Most of his conquests appear to have been limited to the southwestern, ethnically Makassar areas of the peninsula. Gowa may have encountered setbacks from around 1520 to 1540, such as the loss of the upper Talloq River and Garassiq, but these were temporary. By the 1530s, Garassiq had been reconquered and eventually became the seat of the Gowa court, with the royal citadel of Somba Opu possibly first constructed during Tumapaqrisiq Kallonna's reign. Trade in Gowa expanded substantially, partly due to the decline of Majapahit in Java during the fifteenth century and the fall of Malacca to the Portuguese in 1511. The former event shifted the main source of trade in South Sulawesi from Java to western Indonesia and the Malay peninsula, and the latter caused the predominantly Muslim traders from those regions to avoid Malacca and seek other ports such as Gowa.
