Palau is a pristine Pacific paradise featuring the legendary Rock Islands, a UNESCO World Heritage Site with over 200 limestone and coral islands covered in lush greenery. This small nation offers world-class diving, the famous Jellyfish Lake where you can swim among millions of harmless jellyfish, and some of the most biodiverse marine environments on Earth.
Palau's human story spans over 3,000 years, with Austronesian-speaking peoples establishing a sophisticated island culture featuring elaborate meeting houses, a complex money bead system, and advanced maritime skills. Colonial powers—Spain, Germany, Japan, and ultimately the United States—each left profound marks on the islands. The most devastating chapter came during WWII when the Battle of Peleliu (1944) became one of the war's bloodiest Pacific engagements. Palau gained independence from UN Trusteeship in 1994 and has since become a global leader in marine conservation.

Historical eras
The chapters of Palau's past.
Ancient Palauan Period
Austronesian settlers developed a sophisticated island civilization characterized by elaborate storyboard carvings, a complex traditional money bead economy, and skilled ocean navigation using outrigger canoes.
Colonial Period
Successive colonial rulers—Spain, Germany, Japan—each transformed Palau's economy and infrastructure while eroding traditional culture. Japan built the most extensive infrastructure and brought the largest population of settlers before WWII.
WWII Pacific Theater
The Battle of Peleliu and the aerial bombing of Koror left permanent scars on the islands. American forces and Japanese defenders fought a grueling 73-day battle in Peleliu's coral ridges and caves, resulting in massive casualties on both sides.
American Trusteeship and Independence
Under US administration Palau developed modern infrastructure, education, and governance institutions. A protracted negotiation over nuclear-free status delayed the Compact of Free Association until 1994 when Palau became the world's newest nation.
