Walsh. Convicted of accepting bribes from the oil companies, Fall became the first presidential cabinet member to go to prison; no one was convicted of paying the bribes. Before the Watergate scandal, Teapot Dome was regarded as the "greatest and most sensational scandal in the history of American politics".

the great wall of china worked as a defense for the feudal states of the zhou dynasty to the north. during the warring states period more walls were put up to defend the borders of the different kingdoms. it was semi successful because despite the wall, the mongols eventually conquered china also the great wall provided protection to the economic development and cultural progress, safeguarded the trading routes such as the silk road, and secured transmission of information and transportation. @jayxboof
