Former leaders of the Horde
The shadow hunter Vol'jin, son of Sen'jin, chieftain of the Darkspear Trolls, and rightful ruler of the Echo Isles, was a staunch ally of former Warchief Thrall . After the Echo Isles were conquered by the traitorous sorcerer Zalazane, he resided in Orgrimmar at the side of the Warchief, later fighting alongside him during the Battle for the Undercity. After years of exile, Vol'jin led an attack to retake the Echo Islands to end Zalazane's evil rule and retake the lands that Thrall had promised them.
Following Garrosh's defeat in the end of Mists of Pandaria, he assumed the role of Warchief for The Horde.
During the attack on the Broken Shore he was pierced in the abdomen by a fel spear. Badly injured, he was taken back to Orgrimmar where he communed with the Loa who gave him a name, and as he drew his last breath in Grommash Hold, he named the new Warchief:Sylvanas Windrunner.

Garrosh Hellscream was the son of Grom Hellscream and former chieftain of the Warsong Clan. With the reopening of the Dark Portal, Garrosh was invited into the Horde by Thrall himself, quickly advancing to the position of personal adviser of the Warchief. Garrosh led the Horde Troops into Northrend and was given the position of acting Warchief in Thrall's absence.
Garrosh was well known for his fierce hatred of the Alliance and frequently expressed his desire for the Horde to go to war with its rival faction.
Garrosh is the main antagonist of Mists of Pandaria and the secondary antagonist of Warlords of Draenor.
Thrall (birthname Go'el), son of Durotan was the Warchief of the restored Horde and ruler of the red land of Durotar in Kalimdor. Before the Cataclysm, he was Warchief of all the Horde, but temporarily gave leadership to Garrosh in order to lead the Earthen Ring's effort Farseer Nobundo against the Twilight's Hammer cult and elemental imbalance afflicting Azeroth caused by the awakening of Deathwing. After Garrosh's tyranny was overthrown, Thrall renounced his claim on the title of Warchief and instead gave the position to his close friend and ally, Vol'jin.
Former Leaders of the Horde Races
Sen'jin (Former leader of the Darkspear tribe)
Sen'jin and his Darkspear lived in relative peace until they came under attack by Kul'Tiras marines, murlocs and the Naga forces led by the Sea Witch. He saw a vision of a young orc who would save his people, and that vision came true when Thrall's orcish Horde landed on the island the Darkspear called home. They formed an alliance and agreed to help each other.
After a fierce battle in which he was slashed by a Murloc under Underworld Minions as part of a sacrifice, Sen'jin was wounded and was about to meet his demise. With his dying breath, Sen'jin implored Thrall to take his people from the island and save them from destruction. His role as leader was filled by his son, Vol'jin.
Cairne Bloodhoof was the Chief of the united tribes of the Tauren, chieftain of the Bloodhoof tribe, and leader of Thunder Bluff. Allying with the Horde upon its arrival on the shores of Kalimdor, Cairne stood as one of its wisest and most venerated leaders. He wielded the shaman-blessed Bloodhoof Runespear.
He was slain in a botched duel with Garrosh at the hands of Magatha Grimtotem.
