Step-by-step explanation:
The two innovations that broke the dominance of the Greek Aristocracy were the Phalanx and Xenophon.
The Phalanx was a military formation used by the Greeks that consisted of heavily armed infantrymen called hoplites, who would stand shoulder to shoulder with long spears, shields, and armor. This formation allowed for greater coordination and discipline on the battlefield.
Xenophon was a Greek historian and military commander who wrote extensively about warfare and military tactics. His writings, such as the Anabasis, provided valuable insights into military strategy and helped shape the tactics of future armies.
