Mass emigration to the Americas at the outset of the 20th century, famine during World War I that killed an estimated one third to one half of the population, the 1860 Mount Lebanon civil war and the Lebanese Civil War between 1975-90 greatly decreased their numbers in the Levant; however Maronites today form more than one quarter of the total population of modern-day Lebanon. Though concentrated in Lebanon, Maronites also show presence in the neighboring Levant, as well as a significant part in the Lebanese diaspora in the Americas, Europe, Australia, and Africa.
