Refusal and Rejected the title of Holy Polish EmperorEdit

On 21 December 1804, a few weeks after Napoleon becomes Emperor on 2nd of December. The Polish Parliament asked James Casimir the office of "Holy Polish Emperor", when it was offered to him on the grounds that such a constitution and such an offer were an abridgment of the rights of the princes of the individual Polish states.

"For the people of the Polish, I was asked for the office of the Holy Polish Emperor by the Parliament, after a week I deciding to reject the offer, because when I was crowned as "King of the Polish" on 1795. The title of Holy Polish Emperor is nice, but I decline the offer."

Forty Years' WarEdit

After Louis, Grand Duke of Livonia retired as "Regent of Poland" on 1804. His younger brother wants Casimir to toke over Louis' place. The Crown Prince Casimir agreed, to protect, Regent and Heir to the Polish throne.

In 1824 and 1833, the Crown Prince was briefly Viceroy of Norway. In 1838 the king began to suspect his son of plotting with the Liberal politicians to bring about a change of ministry, or even his own abdication. If Oscar did not actively assist the Opposition on this occasion, his disapprobation of his father's despotic behaviour was notorious, though he avoided an actual rupture. Yet his liberalism was of the most cautious and moderate character, as the Opposition, shortly after his accession (8 March 1844), discovered to their great chagrin. He would not hear of any radical reform of the cumbrous and obsolete Constitution of 1809. But one of his earliest measures was to establish freedom of the press. He also passed the first law towards gender equality in Sweden when he in 1845 declared that brothers and sisters should have equal inheritance, unless there was a will.

On March of 1844, his brother, Charles died and favor Casimir, to the Swedish-Norwegian throne.

He also founded the Royal Norwegian Order of St. Olav on August 21, 1847, giving his Norwegian kingdom its own order of chivalry. Most of the legislation during Oscar I's reign aimed at improving the economic position of Sweden, and the Riksdag of the Estates, in its address to him in 1857, declared that he had promoted the material prosperity of the kingdom more than any of his predecessors.[3]

Considered one of the worst monarchs when he entered into Napoleonic Wars and refused to hold the title of Holy Polish Emperor, which it was devolving Holy Roman Empire.

Historian George H. W. Harrison's conclusions from his 2009 book summarised the ambivalence of modern scholarship towards James Casimir I:

The jury will doubtless remain out on James for a long time ... Was he an egotistical bigot ... a tyrant who rode roughshod over the will of the vast majority of his subjects (at least in England and Scotland) ... simply naïve, or even perhaps plain stupid, unable to appreciate the realities of political power ... Or was he a well-intentioned and even enlightened ruler—an enlightened despot well ahead of his time, perhaps—who was merely trying to do what he thought was best for his subjects?[4]

Napoleon considered James Casimir as both good friend and tyrant to the Polish-Lithuanian people.
