Maximilian had intended not only that all these lands should pass into the hands of the Habsburg family, but also that his grandson should succeed him as head of the Holy Roman Empire. This ambition, however, was hard of fulfillment, because the French king, Francis I (1515- 1547), feared the encircling of his own country by a united German- Spanish-Italian state, and set himself to preserve what he called the "Balance of Power"--preventing the undue growth of one political power at the expense of others. It was only by means of appeal to national and family sentiment and the most wholesale bribery that Charles managed to secure a majority of the electors' votes against his French rival [Footnote: Henry VIII of England was also a candidate.] and thereby to acquire the coveted imperial title. He was crowned at Aix- la-Chapelle in his twenty-first year. [Sidenote: Character of Charles] Never have greater difficulties confronted a sovereign than those which Charles V was obliged to face throughout his reign; never did monarch lead a more strenuous life. He was the central figure in a very critical period of history: his own character as well as the painstaking education he had received in the Netherlands conferred upon him a lively appreciation of his position and a dogged pertinacity in discharging its obligations. Both in administering his extensive dominions and in dealing with foreign foes, Charles was a zealous, hard-working, and calculating prince, and the lack of success which attended many of his projects was due not to want of ability in the ruler but to the multiplicity of interests among the ruled. The emperor must do too many things to allow of his doing any one thing well. [Sidenote: Difficulties Confronting Charles]
