This Northern house is one of the last of the Great Houses of Westeros to still have followers, land, and power — and it isn't even led by a true heir, as Jon Snow is a bastard. But the houses of the North don't care that their king isn't a full-blooded Stark (and won't they all be surprised when Jon's true parentage is revealed).
Stark Allies:
The Free Men
The wildlings are no one's bannermen — hence the name, Free Men. But they have come to realize, especially after the bloodbath at Hardhome, that they have to fight alongside the people of Westeros if anyone stands a chance of defeating the Night King and his undead army.
The Vale
After Lysa's untimely death, little Robin may be Lord of the Vale, but it is really his stepfather, Petyr Baelish, who is pulling the strings. He convinces the Knights of the Vale to ride to House Stark's side during the Battle of the Bastards, so for now, the houses of the Vale have thrown in with the North.
However, Baelish has designs on ruling Westeros himself — and he also thinks Sansa Stark is the rightful ruler of the North, so this may be one alliance that is short-lived.
The smaller houses
The smaller houses in the North number in the dozens, though the houses most often mentioned on the show are House Mormont, House Karstark, House Umber, House Manderly, House Reed, and House Glover. Most of them never waivered in their loyalty to the Starks, and the region is still repairing its alliances after some houses had chosen to support Ramsay Bolton as King in the North. Houses Umber and Karstark have since chosen to repledge their loyalty to House Stark now that the Boltons are no longer in power.
The Night's Watch
Like the Free Men, the men of the Night's Watch have no banners or lords. But also like the Free Men, the Night's Watch knows firsthand what is currently marching on Westeros from beyond The Wall, so the men in black will stand alongside their former leader Jon Snow to defeat the White Walkers.
