Christopher Columbus was the first European to sight the islands in 1493. The first settlers were the English in 1623, led by Thomas Warner, who established a settlement at Old Road Town on the west coast of St Kitts after achieving an agreement with the Carib chief Ouboutou Tegremante. The French later also settled on St Kitts in 1625 under Pierre Belain d'Esnambuc. As a result, both parties agreed to partition the island into French and English sectors. From 1628 onward the English also began settling on Nevis.
