Regiment Infanterie Johan Willem Friso
military unit

The Regiment Infantry Prins Johan Willem Friso is a line infantry regiment of the Royal Netherlands Army. Named after Johan Willem Friso of Orange-Nassau, it is the oldest and most senior regiment in the current order of battle. The regiment currently serves in the mechanized infantry role as 44 Armoured Infantry Battalion (44 Painfbat) as part of 43 Gemechaniseerde (Mechanized) Brigade.
Naming
The regiment was formed during the 1950s, in a major reorganisation of the Royal Netherlands Army (Koninklijke Landmacht) after the end of World War II.
Before 1950 the army consisted of numbered regiment; in 1950 these regiments were changed into named regiments.
The Regiment Infantry Johan Willem Friso was created on 1 juli 1950 as a continuation of the former 1st Regiment Infantry (1 RI) and 9th Regiment Infantry (9 RI). Both 1 RI and 9 RI had always been stationed in the North of the Netherlands: 1 RI in Assen (province of Drenthe) and 9 RI in Leeuwarden (province of Friesland). Therefore, it was decided to name the new regiment after the former Stadhouder of Friesland, Groningen and Drenthe: Johan Willem Friso, Prince of Orange (born 14 August 1687 – died 14 July 1711).
In November 2020, the title of "Prince" was added to the name of the regiment, thereby becoming the Regiment Infanterie Prins Johan Willem Friso.
