The Continental Army was created on 14 June 1775 by the Continental Congress as a unified army for the colonies to fight Great Britain, with George Washington appointed as its commander. The army was initially led by men who had served in the British Army or colonial militias and who brought much of British military heritage with them. As the Revolutionary War progressed, French aid, resources, and military thinking influenced the new army. A number of European soldiers came on their own to help, such as Friedrich Wilhelm von Steuben, who taught the army Prussian tactics and organizational skills.
When was the Continental Army created?

Academic higher education in Estonia is divided into three levels: bachelor's, master's, and doctoral studies. In some specialties (basic medical studies, veterinary, pharmacy, dentistry, architect-engineer, and a classroom teacher programme) the bachelor's and master's levels are integrated into one unit. Estonian public universities have significantly more autonomy than applied higher education institutions. In addition to organising the academic life of the university, universities can create new curricula, establish admission terms and conditions, approve the budget, approve the development plan, elect the rector, and make restricted decisions in matters concerning assets. Estonia has a moderate number of public and private universities. The largest public universities are the University of Tartu, Tallinn University of Technology, Tallinn University, Estonian University of Life Sciences, Estonian Academy of Arts; the largest private university is Estonian Business School.
What are the three levels of higher learning in Estonia?

Richard Nixon used national security as a basis for his expansion of power. He asserted, for example, that "the inherent power of the President to safeguard the security of the nation" authorized him to order a wiretap without a judge's warrant. Nixon also asserted that "executive privilege" shielded him from all legislative oversight; furthermore, he impounded federal funds (that is to say, he refused to spend money that Congress had appropriated for government programs). In the specific cases aforementioned, however, the Supreme Court ruled against Nixon. This was also because of an ongoing criminal investigation into the Watergate tapes, even though they acknowledged the general need for executive privilege. Since then, Nixon's successors have sometimes asserted that they may act in the interests of national security or that executive privilege shields them from Congressional oversight. Though such claims have in general been more limited than Nixon's, one may still conclude that the presidency's power has been greatly augmented since the eighteenth and nineteenth centuries.

Under what basis did Richard Nixon assert an expansion of the power of the President?
