Three Founding Families

The term refers to the three Magus families who created a Holy Grail War system. There are two different sets of families for two different Holy Grail Wars.
==Fuyuki Holy Grail War==
The creators of the Fuyuki Holy Grail War are:
*Einzbern
*Matou
*Tohsaka
In Fate/stay night, the three families are the Einzbern, Makiri, and Tohsaka.Fate/stay night - Fate route - Day 13: infinity arms - You're my only starFate/stay night - Heaven's Feel route - Day 4: Avenger - Holy Grail War, the beginning The Einzberns specialize in 'the golden rule of the Rhine', and thus were the best suited to make an imitation of the Holy Grail. The Tohsaka provided a suitable land, the technique to bore a hole into the World, and Nagato Tohsaka was an expert in summoning, while the Makiri were the most skilled with Familiars and provided the strong curse that would become the Command Spells to bind the Servants. As a result, they are families whose members have a higher likelihood of being chosen as Masters.
In the timeline of Fate/Apocrypha, exhausted by the fighting during the Third Holy Grail War, the Three Families failed to stop Darnic Prestone Yggdmillennia and the German Third Reich from stealing the Greater Grail. Each followed a different path following this: the Matou, already in decline, went extinct; the Tohsaka gave up on the Holy Grail and instead prioritized their Martial Arts practice as a means to reach the Root; and the Einzberns rededicated themselves to the original plan, starting work on a new Greater Grail.Fate/Apocrypha Volume 2: Round Dance of Black / Festival of Red - Chapter 3
==Ainsworth Holy Grail War==
The creators of the Ainsworth Holy Grail War are:
*Ainsworth
*Matou
*Unknown
In the parallel world of the Ainsworth family in Fate/kaleid liner PRISMA☆ILLYA, for their goal of saving humanity, it's the Ainsworth family instead who sought the Holy Grail and founded the Holy Grail War.
