When was desalination invented?

Desalination, the process of removing salt from seawater to make it suitable for drinking, has ancient roots, with early methods used by civilizations such as the Greeks and Romans. However, modern desalination techniques began to develop in the 19th century, notably with the invention of the multi-stage flash distillation process in the 1950s, which greatly improved efficiency. Today, desalination technologies continue to evolve, addressing water scarcity issues worldwide.
