Why did king louis-phillippe purchase and then store away eugène delacroix's liberty leading the people?

In that famous painting, Delacroix is depicting an uprising against King Charles X and his government that took place in Paris in July of 1830. As a result of that revolt, the king was eventually overthrown and succeeded by Louis Philippe, Duke of Orléans. In spite of its current universal value and popularity, the painting was severely rejected when Delacroix first exhibited it; it caused a great scandal. Therefore, and even though it had indirectly contributed to Louis Philippe's accession to power, it was hidden from the public view.

2. charlemagne used christianity as a major cornerstone for his rule. cloisters were built all over the empire to act as centers for the (re)population of the vast european wilderness.
