European sailors first saw the islands in 1528. Later, the Spanish and German empires controlled the area. By 1914, Japan took control of the islands.

Inside this circle, the geography is complex and varied.

The lagoon contains many different types of landmasses. There are eleven major islands that correspond to local municipalities. These include islands like Weno, Fefen, Dublon, Uman, Param, and Tsis. Beyond these large islands, there are 46 smaller islands within the lagoon itself. The fringing coral reef also holds 41 additional islands.

This diverse layout creates many different habitats and living spaces for the people of the islands.

Human history in Chuuk stretches back many centuries. Archaeological evidence suggests that people lived on the islands of Feefen and Wééné during the first or second century BC. By the 14th century AD, widespread human settlements appeared across the area. European explorers first arrived in the 16th century. The Spanish navigator Álvaro de Saavedra sighted the islands in 1528. Later, the Spanish Empire claimed the islands as part of the Caroline Islands. However, Spanish control remained mostly nominal until the German Empire took possession in 1899.

In 1914, the Japanese Navy seized the islands during the First World War. Following Germany's defeat, Chuuk became a possession of the Empire of Japan under a mandate. This period transformed the lagoon into a massive military installation. During World War II, Chuuk Lagoon served as the main naval base for the Empire of Japan in the South Pacific. It was often called the "Gibraltar of the Pacific" because of its strength. The Japanese built extensive infrastructure, including five airstrips and several seaplane bases. They also constructed roads, trenches, bunkers, and radar stations to protect their forces.

The lagoon once held a massive concentration of naval power. At anchor, there were battleships, aircraft carriers, cruisers, and submarines. Large battleships like the Yamato and Musashi were stationed there for months in 1943. The Japanese garrison included over 27,000 naval personnel and over 16,000 army men. In February 1944, the United States launched Operation Hailstone. This was a major naval air attack that targeted the lagoon.

The attack sank 12 warships and 32 merchant ships. It also destroyed 275 aircraft. This event turned the lagoon into a massive graveyard of sunken ships.

Today, the area is a significant site for both local life and international tourism. The population of the atoll is approximately 36,158 people. Weno is the largest city, with about 13,700 residents. It serves as both the atoll capital and the state capital. While most people on outer islands focus on subsistence activities, the main industry is now tourism. Specifically, scuba diving is very popular among visitors.

Divers travel from around the world to see the "Ghost Fleet of Truk Lagoon." These are the many intact shipwrecks resting on the seafloor.

Recreational diving offers a unique way to study history and marine biology together. The sunken vessels are scattered mainly around the Dublon, Eten, Fefan, and Uman islands. In the crystal clear water, divers can see decks filled with artifacts. These include fighter aircraft, tanks, motorcycles, and even radios. The wrecks are also heavily encrusted with coral. This creates a habitat for diverse marine life, such as manta rays and turtles.
