As the Imperium expanded its influence, the need for a large and powerful walker became necessary in order to remain militaristically superior. Although the Imperium was using AT-ATs and fast airspeeders to defend its territories, they needed to project an image of power. The Goliath Walker was designed by a consortium of different corporations, manufactured by the Imperium's Testria Weapons Labs, and has thicker armor, more powerful weapons and a higher top speed than the AT-AT, although it costs considerably more. The high cost has meant that the Imperium hasn't ordered a large enough number of these walkers for them to make a major impact on the strength of the Armed Forces, but they are trooped out at ceremonies to show the military might of the Imperium when necessary.
