Passage: Roman government was headed by two consuls, elected annually by the citizens and advised by a senate composed of appointed magistrates. As Roman society was very hierarchical by modern standards, the evolution of the Roman government was heavily influenced by the struggle between the patricians, Rome's land-holding aristocracy, who traced their ancestry to the founding of Rome, and the plebeians, the far more numerous citizen-commoners. Over time, the laws that gave patricians exclusive rights to Rome's highest offices were repealed or weakened, and leading plebeian families became full members of the aristocracy. The leaders of the Republic developed a strong tradition and morality requiring public service and patronage in peace and war, making military and political success inextricably linked. Many of Rome's legal and legislative structures (later codified into the Justinian Code, and again into the Napoleonic Code) can still be observed throughout Europe and much of the world in modern nation states and international organizations. Question: Who eventually became full members of the aristocracy?
leading plebeian families

Passage: In the immediate aftermath of World War II, there occurred several armed incidents between Yugoslavia and the Western Allies. Following the war, Yugoslavia acquired the Italian territory of Istria as well as the cities of Zadar and Rijeka. Yugoslav leadership was looking to incorporate Trieste into the country as well, which was opposed by the Western Allies. This led to several armed incidents, notably attacks by Yugoslav fighter planes on US transport aircraft, causing bitter criticism from the west. From 1945 to 1948, at least four US aircraft were shot down.[better source needed] Stalin was opposed to these provocations, as he felt the USSR unready to face the West in open war so soon after the losses of World War II and at the time when US had operational nuclear weapons whereas USSR had yet to conduct its first test. In addition, Tito was openly supportive of the Communist side in the Greek Civil War, while Stalin kept his distance, having agreed with Churchill not to pursue Soviet interests there, although he did support the Greek communist struggle politically, as demonstrated in several assemblies of the UN Security Council. In 1948, motivated by the desire to create a strong independent economy, Tito modeled his economic development plan independently from Moscow, which resulted in a diplomatic escalation followed by a bitter exchange of letters in which Tito affirmed that Question: What Italian territory did Yugoslavia acquire after the war?
Istria

Passage: During his brief majority reign, Murad IV (16121640) reasserted central authority and recaptured Iraq (1639) from the Safavids. The resulting Treaty of Zuhab of that same year decisively parted the Caucasus and adjacent regions between the two neighbouring empires as it had already been defined in the 1555 Peace of Amasya. The Sultanate of women (16481656) was a period in which the mothers of young sultans exercised power on behalf of their sons. The most prominent women of this period were Kosem Sultan and her daughter-in-law Turhan Hatice, whose political rivalry culminated in Kosem's murder in 1651. During the Koprulu Era (16561703), effective control of the Empire was exercised by a sequence of Grand Viziers from the Koprulu family. The Koprulu Vizierate saw renewed military success with authority restored in Transylvania, the conquest of Crete completed in 1669, and expansion into Polish southern Ukraine, with the strongholds of Khotyn and Kamianets-Podilskyi and the territory of Podolia ceding to Ottoman control in 1676. Question: When was Kosem murdered?
1651
