The immediate chain of events leading to France and the United Kingdom declaring war on Russia on 27 and 28 March 1854 came from the ambition of the French emperor Napoleon III to restore the grandeur of France. He wanted Catholic support that would come his way if he attacked Eastern Orthodoxy, as sponsored by Russia.:103 The Marquis Charles de La Valette was a zealous Catholic and a leading member of the "clerical party," which demanded French protection of the Roman Catholic rights to the holy places in Palestine. In May 1851, Napoleon appointed La Valette as his ambassador to the Porte (the Ottoman Empire).:7–9 The appointment was made with the intent of forcing the Ottomans to recognise France as the "sovereign authority" over the Christian population.:19 Russia disputed this attempted change in authority. Pointing to two more treaties, one in 1757 and the 1774 Treaty of Küçük Kaynarca, the Ottomans reversed their earlier decision, renouncing the French treaty and insisting that Russia was the protector of the Orthodox Christians in the Ottoman Empire.

The actual substance of English law was formally "received" into the United States in several ways. First, all U.S. states except Louisiana have enacted "reception statutes" which generally state that the common law of England (particularly judge-made law) is the law of the state to the extent that it is not repugnant to domestic law or indigenous conditions. Some reception statutes impose a specific cutoff date for reception, such as the date of a colony's founding, while others are deliberately vague. Thus, contemporary U.S. courts often cite pre-Revolution cases when discussing the evolution of an ancient judge-made common law principle into its modern form, such as the heightened duty of care traditionally imposed upon common carriers.

Ah, so.. Louisiana

Nasser's regional position changed unexpectedly when Yemeni officers led by Nasser supporter Abdullah al-Sallal overthrew Imam Badr of North Yemen on 27 September 1962. Al-Badr and his tribal partisans began receiving increasing support from Saudi Arabia to help reinstate the kingdom, while Nasser subsequently accepted a request by Sallal to militarily aid the new government on 30 September. Consequently, Egypt became increasingly embroiled in the drawn-out civil war until it withdrew its forces in 1967. Most of Nasser's old colleagues had questioned the wisdom of continuing the war, but Amer reassured Nasser of their coming victory. Nasser later remarked in 1968 that intervention in Yemen was a "miscalculation".

Ah, so..
North Yemen
