Saya mau tau Republic of Ragusa dari Dubrovnik. Jelaskan dalam bahasa melayu

After the fall of the Ostrogothic Kingdom, the town came under the protection of the Byzantine Empire. Dubrovnik in those medieval centuries had a Roman population. After the Crusades, Dubrovnik came under the sovereignty of Venice (1205–1358), which would give its institutions to the Dalmatian city. After a fire destroyed almost the whole city in the night of August 16, 1296, a new urban plan was developed. By the Peace Treaty of Zadar in 1358, Dubrovnik achieved relative independence as a vassal-state of the Kingdom of Hungary.

Between the 14th century and 1808, Dubrovnik ruled itself as a free state, although it was a vassal from 1382 to 1804 of the Ottoman Empire and paid an annual tribute to its sultan. The Republic reached its peak in the 15th and 16th centuries, when its thalassocracy rivalled that of the Republic of Venice and other Italian maritime republics.

For centuries, Dubrovnik was an ally of Ancona, the other Adriatic maritime republic rival of Venice, which was the Ottoman Empire's chief rival for control of the Adriatic. This alliance enabled the two towns set on opposite sides of the Adriatic to resist attempts by the Venetians to make the Adriatic a "Venetian Bay", also controlling directly or indirectly all the Adriatic ports. Ancona and Dubrovnik developed an alternative trade route to the Venetian (Venice-Austria-Germany): starting in Dubrovnik it went on to Ancona, through Florence and ended in Flanders .

The Republic of Ragusa received its own Statutes as early as 1272, statutes which, among other things, codified Roman practice and local customs. The Statutes included prescriptions for town planning and the regulation of quarantine (for sanitary reasons).

The Republic was an early adopter of what are now regarded as modern laws and institutions: a medical service was introduced in 1301, with the first pharmacy, still operating to this day, being opened in 1317. An almshouse was opened in 1347, and the first quarantine hospital (Lazarete) was established in 1377. Slave trading was abolished in 1418, and an orphanage opened in 1432. A  water supply system, instead of a cistern, was constructed in 1438 by the Neapolitan architect and engineer Onofrio della Cava. He completed the aqueduct with two public fountains. He also built a number of mills along one of its branches.

The city was ruled by the local aristocracy which was of Latin-Dalmatian extraction and formed two city councils. As usual for the time, they maintained a strict system of social classes. The republic abolished the slave trade early in the 15th century and valued liberty highly. The city successfully balanced its sovereignty between the interests of Venice and the Ottoman Empire for centuries.

The languages spoken by the people were the Romance Dalmatian and common Croatian. The latter started to replace Dalmatian little by little since the 11th century among the common people who inhabited the city. Italian and Venetian would become important languages of culture and trade in Dubrovnik. At the same time, Dubrovnik became a cradle of Croatian literature.

The economic wealth of the Republic was partially the result of the land it developed, but especially of seafaring trade. With the help of skilled diplomacy, Dubrovnik merchants travelled lands freely and on the sea the city had a huge fleet of merchant ships (argosy) that travelled all over the world. From these travels they founded some settlements, from India to America, and brought parts of their culture and flora home with them. One of its keys to success was not conquering, but trading and sailing under a white flag with the word  (freedom) prominently featured on it. The flag was adopted when slave trading was abolished in 1418.

Many Conversos, Jews from Spain and Portugal, were attracted to the city. In May 1544, a ship landed there filled exclusively with Portuguese refugees, as Balthasar de Faria reported to King John. During this time there worked in the city one of the most famous cannon and bell founders of his time: Ivan Rabljanin (Magister Johannes Baptista Arbensis de la Tolle). Already in 1571 Dubrovnik sold its protectorate over some Christian settlements in other parts of the Ottoman Empire to France and Venice. At that time there was also a colony of Dubrovnik in Fes in Morocco. The bishop of Dubrovnik was a Cardinal protector in 1571. At that time there were only 16 other countries which had Cardinal protectors; those being France, Spain, Austria, Portugal, Poland, England, Scotland, Ireland, Naples, Sicily, Sardinia, Savoy, Lucca, Greece, Illyria, Armenia and Lebanon.

The Republic gradually declined due to a combination of a Mediterranean shipping crisis and the catastrophic earthquake of 1667 which killed over 5,000 citizens and levelled most of the public buildings, and consequently negatively impacted the whole well-being of the Republic. In 1699, the Republic was forced to sell two mainland patches of its territory to the Ottomans in order to avoid being caught in the clash with advancing Venetian forces. Today this strip of land belongs to Bosnia and Herzegovina and is that country's only direct access to the Adriatic. A highlight of Dubrovnik's diplomacy was the involvement in the American Revolution.

In 1806, the city surrendered to the Napoleonic army, as that was the only way to end a month-long siege by the Russian-Montenegrin fleets (during which 3,000 cannonballs fell on the city). At first, Napoleon demanded only free passage for his troops, promising not to occupy the territory and stressing that the French were friends of Dubrovnik. Later, however, French forces blockaded the harbours, forcing the government to give in and let French troops enter the city. On this day, all flags and coats of arms above the city walls were painted black as a sign of mourning. In 1808, Marshal Auguste de Marmont abolished the republic and integrated its territory first into Napoleon's Kingdom of Italy and later into the Illyrian provinces under French rule. This was to last until 28 January 1814 when the city surrendered to Captain Sir William Hoste leading a body of British and Austrian troops who were besieging the fortress.
