Problem: For a century, the Appalachians were a barrier to the westward expansion of the British colonies. The continuity of the mountain system, the bewildering multiplicity of its succeeding ridges, the tortuous courses and roughness of its transverse passes, a heavy forest, and dense undergrowth all conspired to hold the settlers on the seaward-sloping plateaus and coastal plains. Only by way of the Hudson and Mohawk Valleys, Cumberland Gap, the Wachesa Trail,[undue weight? discuss] and round about the southern termination of the system were there easy routes to the interior of the country, and these were long closed by powerful Native American tribes such as the Iroquois, Creek, and Cherokee, among others. Expansion was also blocked by the alliances the British Empire had forged with Native American tribes, the proximity of the Spanish colonies in the south and French activity throughout the interior.
Who had the Spanish colonies allied with?

Consistent with Calvin's political ideas, Protestants created both the English and the American democracies. In seventeenth-century England, the most important persons and events in this process were the English Civil War, Oliver Cromwell, John Milton, John Locke, the Glorious Revolution, the English Bill of Rights, and the Act of Settlement. Later, the British took their democratic ideals to their colonies, e.g. Australia, New Zealand, and India. In North America, Plymouth Colony (Pilgrim Fathers; 1620) and Massachusetts Bay Colony (1628) practised democratic self-rule and separation of powers. These Congregationalists were convinced that the democratic form of government was the will of God. The Mayflower Compact was a social contract.
What democratic principles were followed by the Plymouth Colony?
A: self-rule and separation of powers

Question: Timber was the chief building material during the Han dynasty; it was used to build palace halls, multi-story residential towers and halls and single-story houses. Because wood decays rapidly, the only remaining evidence of Han wooden architecture is a collection of scattered ceramic roof tiles. The oldest surviving wooden halls in China date to the Tang dynasty (618907 AD). Architectural historian Robert L. Thorp points out the scarcity of Han-era archaeological remains, and claims that often unreliable Han-era literary and artistic sources are used by historians for clues about lost Han architecture.
