Final answer:
The plebeians won concessions from the patricians during the Struggle of the Orders through negotiations and strikes, leading to the establishment of the Tribune office, Plebeian Council, and laws permitting plebeian participation in government and the ability to pass laws via the Plebeian Assembly.
Step-by-step explanation:
During the Struggle of the Orders, the plebeians won concessions from the ruling patricians primarily through negotiations and strikes. This included threats of secession, which pushed the patricians to allow the creation of the office of Tribune, who could veto decisions made by the Senate and consuls. Later, the Plebeian Council was established, which permitted intermarriage between patricians and plebeians, banned debt slavery, and decreed that one of the two consuls had to be plebeian. By 287 BCE, the Plebeian Assembly could pass laws that applied to all Roman citizens, culminating in the integration of plebeians into the political structure, including serving in the Senate and holding elected offices.
