  • Mount Popomanaseu rises 2,435 meters above sea level. This peak stands as the highest point in all of Solomon Islands. The island covers a total land area that makes it the largest by size within the archipelago. Dense tropical rainforest blankets most of the terrain. A mountainous hinterland stretches across the interior regions. The Mbokokimbo River flows as the longest waterway on the island. It winds through the landscape before reaching the ocean. About 155,605 people currently call this place home. They live alongside native marsupials known as grey cuscus. Bats and rodents are the only other mammals present there. Estuarine crocodiles inhabit the shores along the Weather Coast. These reptiles were once found near the north coast airstrip during World War II. Venomous snakes remain rare on the island today.

  • Archaeological finds at Poha Cave date back to between 4500 BC and 2500 BC. People have lived here since those early prehistoric times. During the period from 1200 BC to 800 BC, Austronesian Lapita peoples settled the islands. Their arrival marked a significant shift in human habitation patterns. The indigenous name for the island remains Isatabu. This name persists despite later European naming conventions. Early settlements established themselves throughout the region. Some areas like the Guadalcanal Watersheds contain old village sites. Most of these watersheds covering 376,146 hectares have never been permanently inhabited by modern standards. BirdLife International identified the site as important due to endemic bird species. Chestnut-bellied imperial pigeons nest within the cloud forests. Woodford's rails and Guadalcanal moustached kingfishers thrive in the rainforest canopy. Meek's lorikeets and Guadalcanal honeyeaters find food among the trees. Threats to this biodiversity include logging activities and invasive species.

  • A Spanish expedition led by Álvaro de Mendaña charted the island in 1568. Pedro de Ortega Valencia named it after his home town in Andalusia, Spain. The village of Guadalcanal in Seville province gave the island its identity. Different pronunciations created variations like Guadarcana or Guarcana over time. European settlers, whalers, and missionaries began arriving during the 18th century. Foreign institutions such as forced labour arrived with these outsiders. British authorities confirmed the name Guadalcanal in line with the Spanish town in 1932. The island was variously referred to under different spellings for decades. Germany established a protectorate over the northern Solomons in 1884. In 1893, the British Solomon Islands Protectorate included the island. Germany eventually handed over most of their protectorate to Britain in 1899. Large agricultural plantations specializing in copra were established by Australians by the early 20th century.

  • About 60,000 natives from many parts of the Solomon Islands were indentured between the 1860s and 1890s. They were sent to Australia or Fiji by British authorities to work on plantations. This system continued into the late nineteenth century. German and British powers vied for control of the region during the 1880s. The Germans established a protectorate over the northern Solomons in 1884. The British Solomon Islands Protectorate was proclaimed in 1893. It included the island of Guadalcanal within its boundaries. By the early 20th century, large agricultural plantations specialized in copra production. These operations ran mainly by Australian interests. The island was not seriously affected by World War I. European settlers brought foreign institutions alongside their arrival. Forced labour became an integral part of the colonial economy structure.

  • The Japanese reached Guadalcanal in May 1942. An American reconnaissance mission spotted construction of a Japanese airfield at Lunga Point. Edwin P. Hoyt documented this critical development in his writings. The United States conducted its first amphibious landing of the war on the 7th of August 1942. U.S. Navy Seabees began finishing the airfield immediately after landing. It was then named Henderson Field after a Marine aviator killed during the Battle of Midway. Aircraft operating from the field became known as the Cactus Air Force. They defended the airfield and threatened any Japanese ships that ventured too close. At night, Japanese naval forces frequently shelled the airfield. They delivered troops with supplies using fast destroyers. This reinforcement effort became known as the Tokyo Express. So many ships were sunk that nearby waters came to be called Ironbottom Sound. The naval Battle of Cape Esperance occurred on the 11th of October 1942. Allied naval forces engaged a large Japanese surface force in early November. They sank the battleship Kirishima during the engagement. Remaining Japanese forces were evacuated at Cape Esperance in February 1943. American authorities declared Guadalcanal secure on the 9th of February 1943.

  • The capital of the British Solomon Islands Protectorate moved to Honiara from Tulagi immediately after World War II. In 1952, the high commissioner for the Western Pacific relocated from Fiji to Honiara. The post combined with that of the governor of the Solomon Islands. The airfield which caused fighting in 1942 is now the international airport. It sits about five miles to the east of Honiara. The secondary airfield known as Fighter Two is now the local golf course. About 7,000 Japanese troops remain missing on the island today. Bones of unearthed Japanese soldiers have been found into the 2010s. American and Japanese groups repeatedly visited Guadalcanal to search for remains. The Vilu War Museum houses an outdoor collection of military equipment remains. Several memorials for American, Australian, Fijian, New Zealand, and Japanese soldiers stand there. Aircraft from the war era are displayed within the museum grounds.

  • Long-simmering tensions between Guale people and Malaitan migrants erupted into violence in early 1999. The Guadalcanal Revolutionary Army began terrorizing Malaitans in rural areas. They aimed to force them out of their homes. About 20,000 Malaitans fled to the capital or returned to their home island. Guale residents of Honiara also fled during this period. The city became a Malaitan enclave while the Malaita Eagle Force took over government operations. The Royal Australian Navy deployed vessels to protect expatriate communities. The Pacific Forum negotiated intervention through RAMSI in 2003. Operation Helpem Fren involved Australia, New Zealand, and other Pacific island nations. This regional intervention addressed the civil war tensions that had developed over decades. The conflict reshaped the social fabric of the island significantly.
