There are a number of reasons; however, the main ones are as below:
1- Byzantine Empire's army were outnumbered by Mehmet II's massive troops
2- Byzantine Empire had already been reduced to a city-state inside its strong defensive fortification, so Constantinople was an open target with no support from outside the city
3- The reinforcement from Rome, despite emperor's requests, was delayed (according to some intentionally), and
4- Mehmet II's army finally managed to open big holes in the city walls with massive cannons built by a Hungarian engineer, who had offered his invention to the Byzantine emperor and the emperor could not afford it.
When the Turks entered the city in 1453 there was already nothing left. Thanks to the Fourth Crusade in 1204, who plundered the city for 57 years.
The Fourth Crusade was formed by the Republic of Venice, Holy Roman Empire, France; Montferrat, Champagne, Blois, Amiens, Île-de-France, Saint-Pol, Burgundy, Flanders...
So the sack and destroy of constantinople is nobody's business but the Northern Italians, Germans, French and Flemish Belgians...
The Turks have reconstructed the city and restorated the remaining Byzantian constructions, such as; the Hagia Sophia (transformed into a mosque, currently transformed into a museum by Ataturk), the Aquaduct(http://www.arkeo3d.com/byzantium1200/aquaduct.html) and dozens more etc.
Prof. Arne Effenberger (Byzantine Institute Free University of Berlin) sums up the scene of the sack of constantinople:
"The 4th Crusade was not a real crusade. It was the worst pillage and plunder ever carried out by the Western Christian world against fellow Christians. Their aim was to smash the powerful city of the Bosphorus."
One of the biggest evidence of the plunder have been set into the facade of St Mark's Basilica in Venice, the Horses of Saint Mark which belong to
Constantinople (http://www.arkeo3d.com/byzantium1200/boxes.html).

It was a disease that resembled what we know as the bubonic plague. This horrifying illness hit constantinople in the later years of justinian's reign. This probably arrived from India on ships infested with rats.
cause they wanted to claim it as their land
it feel to the Muslim Ottoman Turks in 1452
They didn't.
1453
No. They left before they did.
Yes they did. They managed to conquer Constantinople in 1204 and formed The Latin Empire of Constantinople until 1261 when The Emperor of Nicea reconquered the City for The Byzantine Empire.
sure. Jerusalem conquered in 1517. constantinople conquered in 1453.
i
its not hard its impossible dont even think about something like that
There were several attempts by Muslim armies to conquer Constantinople before Ottoman Muslim Sultan Mehmet II el-Fatih (the Conqueror) overran the city's defenses in 1453. The Muslims were unable to conquer Constantinople in those attacks because of how well the city is fortified. The Old City of Constantinople is on a small peninsula and the city walls went right up to the water. This meant that no siege weaponry could be used on three sides of the city. Correspondingly, the only land-border of the city was extremely well-fortified and developed. Additionally, since the land border was west-facing, it would require the Muslims, who were generally coming from the east, to move around the city's north or south face and given the defenders of the city enough time to prepare an effective defense.
Constantinople was the capital of the eastern part of the Roman empire so the emperor or "Caesar" who was ruling had the most power.
After the growth of the Ottoman Empire, the state had already reached its pinnacle. This led to the stagnation and decline of the Ottoman Empire, which lasted hundreds of years.
Saint Philip did not want to conquer Italy and was in no position to do so.
The location of Constantinople (now called Istanbul) at the Straits of the Bosporus and Dardanelles (the narrow passage between the Aegean Sea near Greece, and the Black Sea) has been a route for invading armies from both the north and the south.
