Fabidae is a clade in the Apg3 classification, the first in the Eudicotyledons at a level above Order. The Eudicotyledons, also called Eudicots, is the main clade in the Angiospermae consisting of all the Angiospermae except the Amborellanae, Magnolianae and Lilianae. The first clades in the Eudicotyledons are the Orders Ranunculales and Proteales, followed by small Orders like Sabiales, Trochodendrales, Buxales, Gunnerales, Dilleniales, Saxifragales and Vitales. Then follow the big clades Fabidae, Malvidae and Asteridae.
