The literate upper classes of Rome were increasingly Hellenized in their culture during the 3rd century BC.
Among Romans the career of Titus Quinctius Flamininus (died 174 BC), who appeared at the Isthmian Games in Corinth in 196 BC and proclaimed the freedom of the Greek states, was fluent in Greek, stood out, according to Livy, as a great admirer of Greek culture; the Greeks hailed him as their liberator.
There were however, some Romans during the late Republic, who were distinctly anti-Greek, resenting the increasing influence of Greek culture on Roman life, an example being the Roman Censor, Cato the ElderThe lyric poet Quintus Horatius Flaccus was another philhellene.
It is notable his phrase ""Graecia capta ferum victorem cepit et artis intulit agresti Latio"" (Conquered Greece took captive her savage conqueror and brought her arts into rustic Latium).
Roman emperors known for their philhellenism include Nero, Hadrian, Marcus Aurelius and Julian the Apostate. 
The civilization of ancient Greece has been immensely influential on language, politics, educational systems, philosophy, science, and the arts.
It became the "Leitkultur" of the Roman Empire to the point of marginalizing native Italic traditions.
As Horace put it, "Graecia capta ferum victorem cepit et artes / intulit agresti Latio" ("Epistulae" 2.1.156f.)
"Captive Greece took captive her fierce conqueror and instilled her arts in rustic Latium."
Via the Roman Empire, Greek culture came to be foundational to Western culture in general.
The Byzantine Empire inherited Classical Greek culture directly, without Latin intermediation, and the preservation of classical Greek learning in medieval Byzantine tradition further exerted strong influence on the Slavs and later on the Islamic Golden Age and the Western European Renaissance.
A modern revival of Classical Greek learning took place in the Neoclassicism movement in 18th- and 19th-century Europe and the Americas. 
Following the time of the conquest of the last of the independent Greek city-states and Hellenistic (post-Alexandrine) kingdoms, almost all of the world's Greek speakers lived as citizens or subjects of the Roman Empire.
Despite their military superiority, the Romans admired and became heavily influenced by the achievements of Greek culture, hence Horace's famous statement: "Graecia capta ferum victorem cepit" ("Greece, although captured, took its wild conqueror captive").
In the religious sphere, this was a period of profound change.
The spiritual revolution that took place, saw a waning of the old Greek religion, whose decline beginning in the 3rd century BC continued with the introduction of new religious movements from the East.
The cults of deities like Isis and Mithra were introduced into the Greek world.
Greek-speaking communities of the Hellenized East were instrumental in the spread of early Christianity in the 2nd and 3rd centuries, and Christianity's early leaders and writers (notably St Paul) were generally Greek-speaking, though none were from Greece.
However, Greece itself had a tendency to cling to paganism and was not one of the influential centers of early Christianity: in fact, some ancient Greek religious practices remained in vogue until the end of the 4th century, with some areas such as the southeastern Peloponnese remaining pagan until well into the 10th century AD. 
Hellenistic and Roman periods (323 BC–4th century AD).
After a period of confusion following Alexander's death, the Antigonid dynasty, descended from one of Alexander's generals, established its control over Macedon by 276 BC, as well as hegemony over most of the Greek city-states.
From about 200 BC the Roman Republic became increasingly involved in Greek affairs and engaged in a series of wars with Macedon.
Macedon's defeat at the Battle of Pydna in 168 BC signaled the end of Antigonid power in Greece.
In 146 BC Macedonia was annexed as a province by Rome, and the rest of Greece became a Roman protectorate.
The process was completed in 27 BC when the Roman Emperor Augustus annexed the rest of Greece and constituted it as the senatorial province of Achaea.
Despite their military superiority, the Romans admired and became heavily influenced by the achievements of Greek culture, hence Horace's famous statement: "Graecia capta ferum victorem cepit" ("Greece, although captured, took its wild conqueror captive").
Greek science, technology and mathematics are generally considered to have reached their peak during the Hellenistic period.
Greek-speaking communities of the Hellenized East were instrumental in the spread of early Christianity in the 2nd and 3rd centuries, and Christianity's early leaders and writers (notably St Paul) were generally Greek-speaking, though none were from Greece.
Greece itself had a tendency to cling on to paganism and was not one of the influential centers of early Christianity: in fact, some ancient Greek religious practices remained in vogue until the end of the 4th century, with some areas such as the southeastern Peloponnese remaining pagan until well into the 10th century AD.
Slaves ("servi") were not citizens, and lacked even the legal standing accorded free-born foreigners.
For the most part, slaves descended from debtors and from prisoners of war, especially women and children captured during sieges and other military campaigns in Greece, Italy, Spain, and Carthage.
In the later years of the Republic and into the Empire, more slaves came from newly conquered areas of Gaul, Britain, North Africa, and Asia Minor.
Many slaves were created as the result of Rome's conquest of Greece, but Greek culture was considered in some respects superior to that of Rome: hence Horace's famous remark "Graecia capta ferum victorem cepit" ("Captured Greece took her savage conqueror captive").
The Roman playwright Terence is thought to have been brought to Rome as a slave.
Thus slavery was regarded as a circumstance of birth, misfortune, or war; it was defined in terms of legal status, or rather the lack thereof, and was neither limited to or defined by ethnicity or race, nor regarded as an inescapably permanent condition.
Slaves who lacked skills or education performed agricultural or other forms of manual labor.
Those who were violent or disobedient, or who for whatever reason were considered a danger to society, might be sentenced to labor in the mines, where they suffered under inhumane conditions.
Slaves subjected to harsh labor conditions also had few if any opportunities to obtain their freedom.
Since slaves were legally property, they could be disposed of by their owners at any time.
All children born to female slaves were slaves.
Some slave owners, as for instance Tacitus, freed slaves whom they believed to be their natural children.
Slaves who had the education or skills to earn a living were often manumitted upon the death of their owner as a condition of his will.
Slaves who conducted business for their masters were also permitted to earn and save money for themselves, and some might be able to buy their own freedom.
Over time, legislation was passed to protect the lives and health of slaves.
Although many prostitutes were slaves, for instance, the bill of sale for some slaves stipulated that they could not be used for commercial prostitution.
