Capitals
The capital of Perumpadapu Swaroopam was located at Chitrakooda in the Perumpadapu village of Vanneri from the beginning of the 12th century to the end of 13th century. Even though the capital of Perumpadapu Swaroopam was in Vanneri, the Perumpadapu king had a palace in Mahodayapuram.
When the Zamorins attacked Vanneri in the later part of the 13th century, Perumpadapu Swaroopam shifted their capital from Vanneri to Mahodayapuram. In 1405 Perumpadapu Swaroopam changed their capital from Mahodayapuram to Cochin. By the end of the 14th century the Zamorin conquered Thrikkanamathilakam and it became a threat for Mahodayapuram (Thiruvanchikulam), which may be the reason that Perumpadapu Swaroopam changed their capital to Cochin from Mahodayapuram. Moreover, in the year 1341 a flood created an island, Puthuvippu (Vypin), and Cochin became a noted natural harbor for the Indian Ocean trade. The old Kodungallore (Cranganore) port lost its importance, which may also be a cause for the shift of the capital. From there on Perumpadapu Swaroopam used the name Cochin Royal Family.
Finally, the arrival of the Portuguese on the Indian subcontinent in the sixteenth century likely influenced Cochin politics. The Kingdom of Cochin was among the first Indian nations to sign a formal treaty with a European power, negotiating trade terms with Pedro Álvares Cabral in 1500.
The palace at Kalvathhi was originally the residence of the kings. In 1555, though, the royal palace moved to Mattancherry, and later relocated to (Thrissur). At that time Penvazithampuran (Female Thampuran) and the other Kochuthampurans (other Thampurans except the Valliathampuran (King)) stayed at a palace in Vellarapilly.
In the beginning of 18th century Thripunithura started gaining prominence. The kingdom was ruled from Thrissur, Cochin and Thripunithura. Around 1755 Penvazithampuran (Female Thampuran) and the other Kochuthampurans (other Thampurans) left Vellarapalli and started to live in Thripunithura. Thus Thripunithura became the capital of the Cochin Royal Family.
