Explain July revolution and Greek revolution

The French Revolution of 1830, also known as the July Revolution  Second French Revolution or Trois Glorieuses in French ("Three Glorious [Days]"), saw the overthrow of King Charles X, the French Bourbon monarch, and the ascent of his cousin Louis Philippe, Duke of Orléans, who himself, after 18 precarious years on the throne, would in turn be overthrown in 1848. It marked the shift from one constitutional monarchy, under the restored House of Bourbon, to another, the July Monarchy; the transition of power from the House of Bourbon to its cadet branch, the House of Orléans; and the replacement of the principle of hereditary right by popular sovereignty. Supporters of the Bourbon would be called Legitimists, and supporters of Louis Philippe Orléanists.
