Mary, who had passed her early life in the Netherlands under the care of her aunt Margaret, proved herself in every way her worthy successor. She possessed, like Margaret, a strong character, statesmanlike qualities and singular capacity in the administration of affairs. She filled the difficult post of regent for the whole period of twenty-four years between the death of Margaret and the abdication of Charles V in 1555. It was fortunate indeed for that great sovereign that these two eminent women of his house should, each in turn for one half of his long reign, have so admirably conducted the government of this important portion of his dominions, as to leave him free for the carrying out of his far-reaching political projects and constant military campaigns in other lands. Two years after Mary entered upon her regency Charles appointed three advisory and administrative bodies--the Council of State, the Council of Finance and the Privy Council--to assist her in the government. The Council of State dealt with questions of external and internal policy and with the appointment of officials; the Council of Finance with the care of the revenue and private domains of the sovereign; to the Privy Council were entrusted the publication of edicts and "placards," and the care of justice and police. When Charles succeeded Philip the Fair only a portion of the Netherlands was subject to his sway. With steady persistence he set himself to the task of bringing all the seventeen provinces under one sovereign. In 1515 George of Saxe-Meissen sold to him his rights over Friesland. Henry of Bavaria, who in opposition to his wishes had been elected Bishop of Utrecht, was compelled (1528) to cede to him the temporalities of the see, retaining the spiritual office only. Charles thus added the Upper and Lower _Sticht_--Utrecht and Overyssel--to his dominions. He made himself (1536) master of Groningen and Drente after a long and obstinate struggle with Charles of Gelderland, and seven years later he forced Charles' successor, William of Jülich and Cleves, to renounce in his favour his claims to Gelderland and Zutphen. During the reign of Charles V the States-General were summoned many times, chiefly for the purpose of voting subsidies, but it was only on special and solemn occasions, that the representatives of all the seventeen provinces were present, as for instance when Philip received their homage in 1549 and when Charles V announced his abdication in 1555. The names of the seventeen provinces summoned on these occasions were Brabant, Limburg, Luxemburg, Gelderland, Flanders, Holland, Zeeland, Artois, Hainault, Namur, Lille with Douay and Orchies, Tournay and district, Mechlin, Friesland, Utrecht, Overyssel with Drente and Groningen. The bishopric of Liège, though nominally independent, was under the strict control of the government at Brussels. The relations of Charles' Burgundian domains to the empire were a matter of no small moment, and he was able to
