Sciatica can also be caused by tumors impinging on the spinal cord or the nerve roots. Severe back pain extending to the hips and feet, loss of bladder or bowel control, or muscle weakness may result from spinal tumors or cauda equina syndrome. Trauma to the spine, such as from a car accident, may also lead to sciatica.
Republicanism is an ideology centered on citizenship in a state organized as a republic under which the people hold popular sovereignty. [citation needed] Many countries are republics in the sense that they are not monarchies. This article covers only the ideology of republicanism.
American republicanism was founded and first practiced by the Founding Fathers in the 18th century. For them, according to one team of historians, republicanism represented more than a particular form of government. It was a way of life, a core ideology, an uncompromising commitment to liberty, and a total rejection of aristocracy.
