Thiruvananthapuram city and several other places in the district loom large in ancient tradition, folklore and literature.In 1684, during the regency of Umayamma Rani, the English East India Company obtained a sandy spit of land at Anchuthengu near Varkala on the sea coast about 32 kilometres (20 mi) north of Thiruvananthapuram city, with a view to erecting a factory and fortifying it. The place had earlier been frequented by the Portuguese and later by the Dutch. It was from here that the English gradually extended their domain to other parts of Travancore.

Modern history begins with Marthanda Varma, 1729 CE–1758 CE, who is generally regarded as the Father of modern Travancore. Thiruvananthapuram was known as a great center of intellectual and artistic activities in those days.

The temple of Vishnu reclining on Anantha, the Sri Padmanabhaswamy temple, which dates back to the 16th century, is the most-recognizable iconic landmark of the city as well as the district. Along with the presiding deity of Padmanabha, this temple has temples inside it, dedicated to Lord Krishna, Lord Narasimha, Lord Ganesha, and Lord Ayyappa. The temple was built by King Marthanda Varma of the Travancore royal family when, in 1745, he shifted the Travancore capital from Padmanabhapuram, which is now in Tamil Nadu. King Marthanda Varma started reigning as ‘Sree Padmanabhadasa’, the Slave of Sree Padmanabha. The vast temple complex, with its tall Gopuram decorated with detailed carvings reflected in the huge temple tank, is today a center of attraction for the pious, the tourist, and the merely curious.

The city was the capital of the Travancore state before India’s independence. Consequent to the recommendations of the state Reorganization Commission, the Vilavancode taluk from Thiruvananthapuram was merged with Tamil Nadu, along with three other southern taluks of Thovala, Agastheewaram and Kalkulam from Travancore which eventually formed the Kanyakumari district of Tamil Nadu. The state of Kerala came into being on 1 November 1956.

The district stretches 78 kilometres (48 mi) along the shores of the Arabian Sea on the west, Kollam district lies on the north with Tirunelveli and Kanyakumari districts of Tamil Nadu on the east and south respectively.
