=== Ottoman-Safavid War: 1604–06 ===

The [[Ottoman–Safavid War (1603–18)|Ottoman–Safavid War]] had begun shortly before the death of Ahmed's father Mehmed III.  Upon ascending the throne, Ahmed I appointed [[Cigalazade Yusuf Sinan Pasha]] as the commander of the eastern army. The army marched from Constantinople on 15 June 1604, which was too late, and by the time it had arrived on the eastern front on 8 November 1604, the [[Safavid]] army had captured [[Yerevan]] and entered the [[Kars Eyalet]], and could only be stopped in [[Akhaltsikhe]]. Despite the conditions being favourable, Sinan Pasha decided to stay for the winter in [[Van, Turkey|Van]], but then marched to [[Erzurum]] to stop an incoming Safavid attack. This caused unrest within the army and the year was practically wasted for the Ottomans.<ref name=islamans>{{cite encyclopedia |url=https://cdn2.islamansiklopedisi.org.tr/dosya/2/C02000576.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://cdn2.islamansiklopedisi.org.tr/dosya/2/C02000576.pdf |archive-date=2022-10-09 |url-status=live| title=Ahmed I |encyclopedia=İslam Ansiklopedisi |publisher=Türk Diyanet Vakfı |pages=30–33 |year=1989 | volume=1}}</ref>

In 1605, Sinan Pasha marched to take [[Tabriz]], but the army was undermined by [[Köse Sefer Pasha]], the [[Beylerbey]] of Erzurum, marching independently from Sinan Pasha and consequently being taken prisoner by the Safavids. The Ottoman army was routed at [[Battle of Urmia (1604)|Urmia]] and had to flee firstly to Van and then to [[Diyarbakır|Diyarbekir]]. Here, Sinan Pasha sparked a rebellion by executing the Beylerbey of [[Aleppo]], [[Canbulatoğlu Hüseyin Pasha]], who had come to provide help, upon the pretext that he had arrived too late. He soon died himself and the Safavid army was able to capture [[Ganja, Azerbaijan|Ganja]], [[Shirvan]] and [[Shamakhi]] in Azerbaijan.<ref name=islamans/>
