Ahmed I

Ahmed I (Ottoman Turkish: احمد اول Aḥmed-i evvel; Turkish: I. Ahmed; 18 April 1590 – 22 November 1617) was the sultan of the Ottoman Empire from 1603 to 1617. Ahmed's reign is noteworthy for marking the first breach in the Ottoman tradition of royal fratricide; henceforth, Ottoman rulers would no longer systematically execute their brothers upon accession to the throne. He is also well known for his construction of the Blue Mosque, one of the most famous mosques in Turkey.

Ahmed was born at the Manisa Palace, Manisa, probably on 18 April 1590, when his father Şehzade Mehmed was still a prince and the governor of the Sanjak of Manisa. His mother was Handan Sultan. After his grandfather Murad III's death in 1595, his father came to Constantinople and ascended the throne as Sultan Mehmed III. Mehmed ordered the execution of his nineteen half brothers. Ahmed's elder brother Şehzade Mahmud was also executed by his father Mehmed on 7 June 1603, just before Mehmed's own death on 22 December 1603. Mahmud was buried along with his mother (Halime Sultan, dead after 1623) in a separate mausoleum built by Ahmed in Şehzade Mosque, Constantinople.

Ahmed ascended the throne after his father's death in 1603, at the age of thirteen, when his powerful grandmother Safiye Sultan was still alive. With his accession to the throne, the power struggle in the harem flared up; between his mother Handan Sultan and his grandmother Safiye Sultan, who in the previous reign had absolute power within the walls (behind the throne), in the end, with the support of Ahmed, the fight ended in favor of his mother. Ahmed broke with the traditional fratricide following previous enthronements and did not order the execution of his three years old half-brother Mustafa, the second son of Halime Sultan. Instead, Mustafa was sent to live at the old palace at Bayezit along with his mother and their grandmother, Safiye Sultan. This was most likely due to Ahmed's young age - he had not yet demonstrated his ability to sire children, and Mustafa was then the only other candidate for the Ottoman throne. His brother's execution would have endangered the dynasty, and thus he was spared.

His mother tried to interfere in his affairs and influence his decision, especially she wanted to control his communication and movements. In the earlier part of his reign, Ahmed I showed decision and vigor, which were belied by his subsequent conduct.^{[citation needed]} The wars in Hungary and Persia, which attended his accession, terminated unfavourably for the empire. Its prestige was further tarnished in the Treaty of Zsitvatorok, signed in 1606, whereby the annual tribute paid by Austria was abolished. Following the crushing defeat in the Ottoman–Safavid War (1603–1612) against the neighbouring rivals Safavid Empire, led by Shah Abbas the Great, Georgia, Azerbaijan and other vast territories in the Caucasus were ceded back to Persia per the Treaty of Nasuh Pasha in 1612, territories that had been temporarily conquered in the Ottoman–Safavid War (1578–90). The new borders were drawn per the same line as confirmed in the Peace of Amasya of 1555.

During his reign the ruler of Morocco was Mulay Zidan whose father and predecessor Ahmad al-Mansur had paid a tribute of vassalage as a vassal of the Ottomans until his death. The Saadi civil wars had interrupted this tribute of vassalage, but Mulay Zidan proposed to submit to it in order to protect himself from Algiers, and so he resumed paying the tribute to the Ottomans.

The 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, 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.

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 Urmia and had to flee firstly to Van and then to 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, Shirvan and Shamakhi in Azerbaijan.

The Long Turkish War between the Ottomans and the Habsburg monarchy had been going on for over a decade by the time Ahmed ascended the throne. Grand Vizier Malkoç Ali Pasha marched to the western front from Constantinople on 3 June 1604 and arrived in Belgrade, but died there, so Sokolluzade Lala Mehmed Pasha was appointed as the Grand Vizier and the commander of the western army. Under Mehmed Pasha, the western army recaptured Pest and Vác, but failed to capture Esztergom as the siege was lifted due to unfavourable weather and the objections of the soldiers. Meanwhile, the Prince of Transylvania, Stephen Bocskay, who struggled for the region's independence and had formerly supported the Habsburgs, sent a messenger to the Porte asking for help. Upon the promise of help, his forces also joined the Ottoman forces in Belgrade. With this help, the Ottoman army besieged Esztergom and captured it on 4 November 1605. Bocskai, with Ottoman help, captured Nové Zámky (Uyvar) and forces under Tiryaki Hasan Pasha took Veszprém and Palota. Sarhoş İbrahim Pasha, the Beylerbey of Nagykanizsa (Kanije), attacked the Austrian region of Istria. However, with Jelali revolts in Anatolia more dangerous than ever and a defeat in the eastern front, Mehmed Pasha was called to Constantinople. Mehmed Pasha suddenly died there, whilst preparing to leave for the east. Kuyucu Murad Pasha then negotiated the Peace of Zsitvatorok, which abolished the tribute of 30,000 ducats paid by Austria and addressed the Habsburg emperor as the equal of the Ottoman sultan. The Jelali revolts were a strong factor in the Ottomans' acceptance of the terms. This signaled the end of Ottoman growth in Europe.
