Editing 1840s (section)

==== Spain ====
{{Main|Carlist Wars}}This period saw the 1840 end of the [[First Carlist War]], a [[civil war]] in [[Spain]] over the succession to the throne and the nature of the [[Monarchy of Spain|Spanish monarchy]]. This was the first full decade of the [[reign of Isabella II of Spain]]. Since she was only 10 years old in 1840, her true reign started in 1843, for which the first portion was referred to as [[Década moderada]]. The [[Affair of the Spanish Marriages]] (1846) was a series of intrigues between [[July Monarchy|France]], [[Mid-nineteenth century Spain|Spain]], and the [[United Kingdom of Great Britain and Ireland|United Kingdom]] relating Isabella II's marriages, which was shortly followed by [[Second Carlist War]] (1847–1849).
