On 15 November 1577, Francis Drake began a circumnavigation which would last for 1046 days. Before this journey, only a single expedition had completed a circumnavigation, one pioneered by Ferdinand Magellan. On Drake's voyage, Drake was the first Englishman to navigate out of the south Atlantic Ocean and during the journey, he established the first overseas possession claims executed during the reign of Queen Elizabeth I. At its completion, this was the longest voyage humans had made to date.
