Primogeniture , in which the eldest child of the monarch is first in line to become monarch, is the most common system in hereditary monarchy. The order of succession is usually affected by rules on gender. Historically "agnatic primogeniture" or "patrilineal primogeniture" was favoured, that is inheritance according to seniority of birth among the sons of a monarch or head of family , with sons and their male issue inheriting before brothers and their issue, and male-line males inheriting before females of the male line.  This is the same as semi-Salic primogeniture. Complete exclusion of females from dynastic succession is commonly referred to as application of the Salic law (see Terra salica ).
Some people believe that a country calling itself a democracy must be engaged in direct (or pure) democracy, in which the people of a state or region vote directly for policies, rather than elect representatives who make choices on their behalf. People who follow this line of reasoning hold that the United States is more properly described as a republic , using the following definition of that word: ”a government in which supreme power resides in a body of citizens entitled to vote and is exercised by elected officers and representatives responsible to them and governing according to law.”
