The clergy was divided into two types: the secular clergy, who lived out in the world, and the regular clergy, who lived under a religious rule and were usually monks. Throughout the period monks remained a very small proportion of the population, usually less than one per cent. Most of the regular clergy were drawn from the nobility, the same social class that served as the recruiting ground for the upper levels of the secular clergy. The local parish priests were often drawn from the peasant class. Townsmen were in a somewhat unusual position, as they did not fit into the traditional three-fold division of society into nobles, clergy, and peasants. During the 12th and 13th centuries, the ranks of the townsmen expanded greatly as existing towns grew and new population centres were founded. But throughout the Middle Ages the population of the towns probably never exceeded 10 per cent of the total population.
From what class were many parish priests?
the peasant class

The last three years of Eisenhower's second term in office were ones of relatively good health. Eventually after leaving the White House, he suffered several additional and ultimately crippling heart attacks. A severe heart attack in August 1965 largely ended his participation in public affairs. In August 1966 he began to show symptoms of cholecystitis, for which he underwent surgery on December 12, 1966, when his gallbladder was removed, containing 16 gallstones. After Eisenhower's death in 1969 (see below), an autopsy unexpectedly revealed an adrenal pheochromocytoma, a benign adrenaline-secreting tumor that may have made the President more vulnerable to heart disease. Eisenhower suffered seven heart attacks in total from 1955 until his death.
For what ailment did Eisenhower receive surgery in 1966?
cholecystitis

During the night of December 2 and early morning of December 3, 1968, Kerry was in charge of a small boat operating near a peninsula north of Cam Ranh Bay together with a Swift boat (PCF-60). According to Kerry and the two crewmen who accompanied him that night, Patrick Runyon and William Zaladonis, they surprised a group of Vietnamese men unloading sampans at a river crossing, who began running and failed to obey an order to stop. As the men fled, Kerry and his crew opened fire on the sampans and destroyed them, then rapidly left. During this encounter, Kerry received a shrapnel wound in the left arm above the elbow. It was for this injury that Kerry received his first Purple Heart Medal.
