Question: One hundred years after the fall of Constantinople in 1453, Pierre Belon described in his work Observations in 1553 that pissasphalto, a mixture of pitch and bitumen, was used in Dubrovnik for tarring of ships from where it was exported to a market place in Venice where it could be bought by anyone. An 1838 edition of Mechanics Magazine cites an early use of asphalt in France. A pamphlet dated 1621, by "a certain Monsieur d'Eyrinys, states that he had discovered the existence (of asphaltum) in large quantities in the vicinity of Neufchatel", and that he proposed to use it in a variety of ways – "principally in the construction of air-proof granaries, and in protecting, by means of the arches, the water-courses in the city of Paris from the intrusion of dirt and filth", which at that time made the water unusable. "He expatiates also on the excellence of this material for forming level and durable terraces" in palaces, "the notion of forming such terraces in the streets not one likely to cross the brain of a Parisian of that generation". But it was generally neglected in France until the revolution of 1830. Then, in the 1830s, there was a surge of interest, and asphalt became widely used "for pavements, flat roofs, and the lining of cisterns, and in England, some use of it had been made of it for similar purposes". Its rise in Europe was "a sudden phenomenon", after natural deposits were found "in France at Osbann (BasRhin), the Parc (l'Ain) and the Puy-de-la-Poix (Puy-de-Dome)", although it could also be made artificially. One of the earliest uses in France was the laying of about 24,000 square yards of Seyssel asphalt at the Place de la Concorde in 1835.
Is there an answer to this question: After what event in France did  asphalt begin to be used for pavements and assorted other uses?

Answer: revolution of 1830

Question: Following the adoption of UN Resolution 390A(V) in December 1950, Eritrea was federated with Ethiopia under the prompting of the United States. The resolution called for Eritrea and Ethiopia to be linked through a loose federal structure under the sovereignty of the Emperor. Eritrea was to have its own administrative and judicial structure, its own flag, and control over its domestic affairs, including police, local administration, and taxation. The federal government, which for all intents and purposes was the existing imperial government, was to control foreign affairs (including commerce), defense, finance, and transportation. The resolution ignored the wishes of Eritreans for independence, but guaranteed the population democratic rights and a measure of autonomy.
