The modern Alliance is the successor to the Alliance of Lordaeron, which was created at the behest of King Terenas Menethil II of Lordaeron and Lord Anduin Lothar of the kingdom of Stormwind following the First War, five years after the reckoning. The human, dwarf, gnome, and high elf races allied together to fight off the orcish Horde.
Events of the Second Invasion led to an alliance with both the night elves and the Horde. The former became permanent, while the latter did not.Following the Second Invasion, many of the surviving high elves rebranded themselves as blood elves, and left the Alliance shortly after the invasion, following an attempted purge by Grand Marshall Garithos. The true high elves remain loyal to the new Alliance, most notably the ones dwelling in Theramore under Lady Jaina Proudmoore and in the Hinterlands at Quel'Danil Lodge. More recently, high elves have grouped together in Northrend as the Silver Covenant.
A few years later, the draenei joined the Alliance. Stranded a world away from home, they are trying to establish a new base on Azeroth from the ruins of the Exodar as well as gain the trust and cooperation of the Alliance.
During the events of the Cataclysm, another race joined the ranks of the Alliance; the worgen of Gilneas.
The Alliance is proud of itself. Their people are sophisticated and learned, and they excel in the intellectual pursuits such as arcane magic and engineering. Even after three bloody wars, they still view themselves as overall smarter than the Horde, and believe that greater brain power wins out over primal force.
Though their powerful command of the arcane is a point of strength in the Alliance’s arsenal, it also shows a weakness. The magi are weak and easy to kill, if an enemy can break through their protections.
The front lines of the Alliance’s armies are always in danger against the physically stronger Horde, especially the orcs and tauren Draenei are stronger then most of Alliance races, but not as strong as orcs or tauren. Only the arrival of Worgen in Cataclysm will probably add a brute force to Alliance.
Though the Alliance has a vast amount of territory, its distribution is almost one sided, most of the Alliance territory is in the Eastern Kingdoms. The Alliance presence in Kalimdor is weak, confined mainly to Teldrassil, the islands of Azuremyst and Bloodmyst, and Darkshore.
Technologically speaking, the Alliance is strong, with gnomish and dwarven inventions.
Heavily armored vehicles with massive guns often help take well-defended structures, or even serve to simply destroy an enemy’s morale. The appearance of three or four armored vehicles can often break an enemy’s morale without ever firing a shot. However, they are well armed in case they do need to fire.
Strategy in combat is the first step toward winning, and the Alliance uses to its fullest. They take advantage of their typical numerical advantage, to overwhelm opposition with shield and sword. They posses great Arcane spell casters which can be seen taking out many troops single-handedly from behind the front line.
Most Alliance races are well-versed in the ways of the holy light, making their paladins and priests formidable opponents. The power of the holy light is also advantageous against the Forsaken as well as other forms of undead due to their extreme weakness against the power with spells such as Exorcism.
The Alliance has strong unity between its races since its core members have been allied together since the beginning, excluding the night elves and the draenei. The humans, dwarves, high elves, and gnomes have been allies since the Second War and are often tied together.
The Alliance represents older bonds of brotherhood than the Horde, especially between the humans, dwarves, high elves, and gnomes. And while the draenei are new to Azeroth, the other races retain ancient holdings. This stands in stark contrast to the Horde, all of whom, with the exception of the blood elves, have undergone significant migrations in the past decade.
