Editing Owain Glyndŵr (section)

===Prequel to rebellion===
In the late 1390s, a series of events occurred which cornered Owain, and forced his ambitions towards a rebellion. The events would later be called the Welsh Revolt, the Glyndŵr Rising (within Wales), or the Last War of Independence. His neighbour, [[Reynold Grey, 3rd Baron Grey of Ruthin|Baron Grey of Ruthin]], had seized control of some land, for which Glyndŵr appealed to the [[Parliament of England|English Parliament]], however, Owain's petition for redress was ignored. Later, in 1400, Lord Grey did not inform Glyndŵr in time about a royal command to levy feudal troops for Scottish border service, thus enabling him to call Glyndŵr a traitor in London court circles.{{sfn|Allday|1981|p=51}} Lord Grey had stature in the royal court of Henry IV. The law courts refused to hear the case, or it was delayed because Lord Grey prevented Owain's letter from reaching the King, which would have repercussions.{{sfn|Davies|Morgan|2009|page=32}} Sources state that Glyndŵr was under threat because he had written an angry letter to Lord Grey, boasting that lands had come into his possession, and he had stolen some of Lord Grey's horses; and believing Lord Grey had threatened to "burn and slay" within his lands, he threatened retaliation in the same manner. Lord Grey then denied making the initial threat to burn and slay, and replied that he would take the incriminating letter to Henry IV's council and that Glyndŵr would hang for the admission of theft and treason contained within the letter.{{sfn|Mortimer|2013|pp=226-}} The deposed king, Richard II, had support in Wales, and in January 1400 serious civil disorder broke out in the English border city of Chester after the public execution of an officer of Richard II.{{sfn|Davies|Morgan|2009|page=34}}{{sfn|Skidmore|1978|p=24}}
