In parliamentary systems, governments are generally required to have the confidence of the lower house of parliament (though a small minority of parliaments, by giving a right to block supply to upper houses, in effect make the cabinet responsible to both houses, though in reality upper houses, even when they have the power, rarely exercise it). Where they lose a vote of confidence, have a motion of no confidence passed against them, or where they lose supply, most constitutional systems require either:
Most parliamentary governments need to have the support of what governmental body?

The first and last Roman known as a living divus was Julius Caesar, who seems to have aspired to divine monarchy; he was murdered soon after. Greek allies had their own traditional cults to rulers as divine benefactors, and offered similar cult to Caesar's successor, Augustus, who accepted with the cautious proviso that expatriate Roman citizens refrain from such worship; it might prove fatal. By the end of his reign, Augustus had appropriated Rome's political apparatus and most of its religious cults within his "reformed" and thoroughly integrated system of government. Towards the end of his life, he cautiously allowed cult to his numen. By then the Imperial cult apparatus was fully developed, first in the Eastern Provinces, then in the West. Provincial Cult centres offered the amenities and opportunities of a major Roman town within a local context; bathhouses, shrines and temples to Roman and local deities, amphitheatres and festivals. In the early Imperial period, the promotion of local elites to Imperial priesthood gave them Roman citizenship.
What form of government did Cesar seem to be attempting?
divine monarchy

Napoleon acknowledged one illegitimate son: Charles Leon (18061881) by Eleonore Denuelle de La Plaigne. Alexandre Colonna-Walewski (18101868), the son of his mistress Maria Walewska, although acknowledged by Walewska's husband, was also widely known to be his child, and the DNA of his direct male descendant has been used to help confirm Napoleon's Y-chromosome haplotype. He may have had further unacknowledged illegitimate offspring as well, such as Eugen Megerle von Muhlfeld by Emilie Victoria Kraus and Helene Napoleone Bonaparte (18161907) by Albine de Montholon.
DNA from Alexandre Colonna-Walewski's descendants has been used to confirm what attribute of Napoleon's?
