beginning of a series of events that would ultimately lead to the fall of the Byzantine capital. The crusaders, diverted from their original mission to reclaim <a href="/wiki/Jerusalem" title="Jerusalem">Jerusalem</a>, found themselves in Constantinople, in support of the deposed emperor <a href="/wiki/Isaac_II_Angelos" title="Isaac II Angelos">Isaac II Angelos</a> and his son <a href="/wiki/Alexios_IV_Angelos" title="Alexios IV Angelos">Alexios IV Angelos</a>. The besieging forces, primarily composed of Western European knights faced initial setbacks, but their determination and advanced siege weaponry played a pivotal role in pressuring the Byzantine defenders. </p><p>Amidst the chaos, the Byzantine emperor was overthrown, leading to a power vacuum and setting the stage for the more infamous events of 1204 when the crusaders, frustrated by unpaid debts and political turmoil, eventually <a href="/wiki/Sack_of_Constantinople" title="Sack of Constantinople">sacked the city</a>. This marked the first time in nearly nine centuries that Constantinople fell to an external force, forever altering the course of Byzantine history. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Siege">Siege</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Siege_of_Constantinople_(1203)&action=edit&section=1" title="Edit section: Siege"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>To take the city by force, the Crusaders first needed to cross the <a href="/wiki/Bosphorus" class="mw-redirect" title="Bosphorus">Bosphorus</a>. About 200 ships, horse transports and galleys would undertake to deliver the crusading army across the narrow strait, where <a href="/wiki/Alexios_III_Angelos" title="Alexios III Angelos">Alexios III</a> had lined up the Byzantine army in battle formation along the shore, north of the suburb of Galata. The Crusaders' knights charged straight out of the horse transports, and the Byzantine army fled south. The Crusaders followed south, and attacked the <a href="/wiki/Galata_Tower_(old)" class="mw-redirect" title="Galata Tower (old)">Tower of Galata</a>, which held one end of the chain that blocked access to the Golden Horn.

On one occasion the defenders sallied out but were unable to retreat back to the safety of the tower in time, the Crusader forces viciously counterattacked, with most of the defenders being cut down or drowning in the Bosporus in their attempts to escape.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> The Golden Horn now lay open to the Crusaders, and the Venetian fleet entered. </p><p>On 11 July the Crusaders took positions opposite the Blachernae palace on the northwest corner of the city. <a href="/wiki/Alexios_IV" class="mw-redirect" title="Alexios IV">Alexios IV</a> was paraded outside the walls, but the citizens were apathetic, as Alexios III, though a usurper and illegitimate in the eyes of the westerners, was an acceptable emperor for the Byzantine citizens. The siege began in earnest on 17 July, with four divisions attacking the land walls, while the Venetian fleet attacked the sea walls from the Golden Horn. The Venetians took a section of the wall of about 25 towers, while the <a href="/wiki/Varangian_Guard" title="Varangian Guard">Varangian Guard</a> held off the Crusaders<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> on the land wall. The Varangians shifted to meet the new threat, and the Venetians retreated under the screen of fire. The fire lasted for 3 days and destroyed about 440 acres (1.8 km<sup>2</sup>) of the city, leaving 20,000 people homeless.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-fire_9-0" class="reference"><a href="#cite_note-fire-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> </p><p>Alexios III finally took offensive action, and led 17 divisions from the St. Romanus Gate, vastly outnumbering the Crusaders. Alexios III's army of about 8,500 men faced the Crusader's 7 divisions (about 3,500 men), but (according to Choniates and the Latins) his courage failed, and the Byzantine army returned to the city without a fight.<sup id="cite_ref-battle2_10-0" class="reference"><a href="#cite_note-battle2-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> </p><p>On 18 July 1203 the Crusaders launched an assault on the city, and Alexios III immediately fled into Thrace.

Emperor Alexios V then attempted to negotiate with the Crusaders for a withdrawal from Byzantine territory, but they refused to abandon their old treaty with Alexios IV. When Alexios V ordered Alexios IV's execution on 8 February, the Crusaders declared war on Alexios V.
