Nagykanizsa (ˈnɒckɒniʒɒ; Velika Kaniža/Velika Kanjiža, or just Kaniža/Kanjiža; Großkirchen, Groß-Kanizsa; Canissa; Velika Kaniža; Kanije), known colloquially as Kanizsa, is a medium-sized city in Zala County in southwestern Hungary. It is a city with county rights.
It lies not far from Lake Balaton at the meeting point of five routes. For centuries the town has been a connecting link. Goods from Slavonia were transported to Graz via Nagykanizsa, and the town played an important role in the trade from the Adriatic Sea to the Alpine region, Vienna, and Budapest.
The city's oldest Roman-era ruins were excavated in the 1960s. During the Middle Ages, Nagykanizsa became one of the most important strongholds of the Hungarian Kingdom. The fortress had a significant role in the southern shield-line of Hungary, guarding the whole of Western Europe against attacks by the Ottoman Empire.
The name Kanizsa was first mentioned in a document in 1245. The Kanizsai family continued building the castle and constructed a rectangular castle with an enclosed back yard on an islet in the River Kanizsa. The town and the castle were in their prime in the first half of the 16th century, when Kanizsa became a centre of trade with Italy and Styria.
Szigetvár and Kanizsa became the most important strongholds in southern Hungary. In 1600, the Turkish army occupied the castle. This castle was the center of an Ottoman eyalet including the sanjaks of Sigetvar, Kopan, Valpuva, Siklos, Nadaj, and Balatin until 1690 (see Ottoman Hungary), when the city was invaded by the Habsburg armies.
In 1601, during the Ottoman-Habsburg War of 1593–1606, a siege began on September 9 and ended on November 18. The Habsburg forces were commanded by Ferdinand, the Archduke of Austria, and Tiryaki Hasan Pasha commanded the defence of the castle. Hasan Pasha won the fight against the ten-times larger army of Austrians with many cunning military ploys, and was raised to the rank of Vizier.
At the beginning of the 18th century, the holder of the castle moved German, Croatian, and Serbian settlers into the deserted town.
