Lagari

Lagari refers primarily to Lagari Hasan Çelebi, a figure in Ottoman folklore described as a pioneer of rocketry. According to legends recorded in later centuries, in 1633 he launched a rocket-propelled vessel from Istanbul and returned safely, purportedly carrying an emblem of the Ottoman state to prove the flight. Modern historians regard the tale as myth, with no contemporary Ottoman sources confirming the flight. The Lagari story has influenced representations of early rocket concepts and has been cited in studies of the history of ideas about flight in the pre-modern world.

The name Lagari is also found as a personal name and, less commonly, as a toponym in parts of the former Ottoman sphere and beyond. In some regions it is used as a surname; in others, place names bearing Lagari are small rural settlements with no widely documented significance. Etymology is uncertain; it may derive from Turkic roots meaning something like "eagle" or "swift", but this is speculative.
