The Iconian Resistance was not exactly an alliance based on territory, but a resistance movement composed of several interstellar governments, formed to oppose the returning Iconians and their servitor races who sought to conquer the galaxy, leading to what became known as the Iconian War of 2410. It consisted of forces from the Alpha, Beta and Delta Quadrants, and ultimately involved the Gamma Quadrant as well. (STO video game: The Iconian War)
