For comparison, this is about 7 times as many as in the entire Caribbean. Most recently, Bali was the host of the 2011 ASEAN Summit, 2013 APEC and Miss World 2013. Bali is the home of the Subak Irrigation System, a UNESCO World Heritage Site. It is also home to a unified confederation of kingdoms, composed of 10 traditional royal Balinese houses, where each house rules a specific geographic area. the confederation is the successor of the Bali Kingdom.

Bali was inhabited around 2000 BC by Austronesian people who migrated originally from Southeast Asia and Oceania through Maritime Southeast Asia. Culturally and linguistically, the Balinese are closely related to the people of the Indonesian archipelago, Malaysia, the Philippines and Oceania. Stone tools dating from this time have been found near the village of Cekik in the island's west.
In ancient Bali, nine Hindu sects existed, namely Pasupata, Bhairawa, Siwa Shidanta, Waisnawa, Bodha, Brahma, Resi, Sora and Ganapatya. Each sect revered a specific deity as its personal Godhead.
Inscriptions from 896 and 911 don't mention a king, until 914, when Sri Kesarivarma is mentioned. They also reveal an independent Bali, with a distinct dialect, where Buddhism and Sivaism were practiced simultaneously. Mpu Sindok's great-granddaughter, Mahendradatta (Gunapriyadharmapatni), married the Bali king Udayana Warmadewa (Dharmodayanavarmadeva) around 989, giving birth to Airlangga around 1001. This marriage also brought more Hinduism and Javanese culture to Bali. Princess Sakalendukirana appeared in 1098. Suradhipa reigned from 1115 to 1119, and Jayasakti from 1146 until 1150. Jayapangus appears on inscriptions between 1178 and 1181, while Adikuntiketana and his son Paramesvara in 1204.
Balinese culture was strongly influenced by Indian, Chinese, and particularly Hindu culture, beginning around the 1st century AD. The name Bali dwipa ("Bali island") has been discovered from various inscriptions, including the Blanjong pillar inscription written by Sri Kesari Warmadewa in 914 AD and mentioning "Walidwipa". It was during this time that the people developed their complex irrigation system subak to grow rice in wet-field cultivation. Some religious and cultural traditions still practiced today can be traced to this period.
The Hindu Majapahit Empire (12931520 AD) on eastern Java founded a Balinese colony in 1343. The uncle of Hayam Wuruk is mentioned in the charters of 138486. A mass Javanese immigration to Bali occurred in the next century when the Majapahit Empire fell in 1520. Bali's government then became an independent collection of Hindu kingdoms which led to a Balinese national identity and major enhancements in culture, arts, and economy. The nation with various kingdoms became independent for up to 386 years until 1906, when the Dutch subjugated and repulsed the natives for economic control and took it over.
