What the name Louis means

The name enters recorded history with Clovis I (c. 466-511), the Merovingian king whose conversion to Christianity established the Frankish world as a Catholic power; Clovis is simply an earlier Latinization of the same Hludwig.

Eighteen French kings would bear the name, culminating in Louis XVI, executed in 1793. Saint Louis IX (1214-1270), canonized in 1297, became the patronal figure and lent his name to the Missouri city founded by French colonists in 1764.

Literary bearers include Robert Louis Stevenson, author of Treasure Island (1883), and the protagonist Louis de Pointe du Lac in Anne Rice’s Interview with the Vampire (1976).

The Sun King, Louis XIV, reigned for 72 years and reshaped European court culture from Versailles.

Brought to North America by French settlers in Quebec, Louisiana, and the Mississippi Valley, the name entered broad American use by the late nineteenth century. U.S.

Social Security records place Louis in the top 30 from 1880 through the 1920s, peaking at rank 21 in 1915. After a long decline, the name has rebounded since 2010, returning to the top 300 as parents revisit classical French forms.

Contemporary bearers include jazz icon Louis Armstrong (1901-1971), chemist Louis Pasteur, and British singer Louis Tomlinson of 1 Direction. Prince Louis of Wales, born in 2018, has renewed the name’s royal visibility in the English-speaking world.
