Segrià (Western Catalan:[seɣɾiˈa]) is a comarca (county) in Catalonia (Spain). It is located in the western region of Ponent, bordering Aragon. As of 2001, over two thirds of its population live in the capital city of Lleida, which is also Catalonia's sixth largest municipality, and remains the most populated comarca in the Ponent region and the Lleida province. It takes its name from the river Segre.
Ponent, also known as the Lleida region following the vegueries law, is the westernmost of the eight regions (vegueries) defined by the Regional Plan of Catalonia. It has an area of 5,586 km, and 365,289 inhabitants as of 2022.
Lleida is one of the oldest towns in Catalonia, with recorded settlements dating back to the Bronze Age period. Until the Roman conquest of the Iberian Peninsula, the area served as a settlement for an Iberian people, the Ilergetes. The town became a municipality, named Ilerda, under the reign of Augustus. It was ruled by Muslims from the 8th century until reconquered in 1149. In 1297, the University of Lleida was founded, becoming the third oldest in the whole of Spain. During the following centuries, the town was damaged by several wars such as the Reapers' War in the 17th century and the Spanish Civil War in the 20th century. Since then, the city has been in constant urban, commercial and demographic growth.
