The Curta is a small mechanical calculator developed by Curt Herzstark. The Curta's design is a descendant of Gottfried Leibniz's Stepped Reckoner and Charles Thomas's Arithmometer, accumulating values on cogs, which are added or complemented by a stepped drum mechanism. It has an extremely compact design: a small cylinder that fits in the palm of the hand.
Samo founded the first recorded political union of Slavic tribes, known as Samo's Empire, stretching from Silesia to present-day Slovenia, ruling from 623 until his death in 658. According to Fredegarius, the only contemporary source, Samo was a Frankish merchant who unified several Slavic tribes against robber raids and violence by nearby settled Avars, showing such bravery and command skills in battle that he was elected as the "Slavic king". In 631, Samo successfully defended his realm against the Frankish Kingdom in the three-day Battle of Wogastisburg.
Ajtony, Ahtum or Achtum was an early-11th-century ruler in the territory now known as Banat in present Romania and Serbia. His primary source is the Long Life of Saint Gerard, a 14th-century hagiography. Ajtony was a powerful ruler who owned many horses, cattle and sheep and was baptised according to the Orthodox rite in Vidin. He taxed salt which was transferred to King Stephen I of Hungary on the Mureș River. The king sent Csanád, Ajtony's former commander-in-chief, against him at the head of a large army. Csanád defeated and killed Ajtony, occupying his realm. In the territory, at least one county and a Roman Catholic diocese were established.

The South Slavs are a subgroup of Slavic peoples who speak the South Slavic languages. They inhabit a contiguous region in the Balkan Peninsula and the eastern Alps, and in the modern era are geographically separated from the body of West Slavic and East Slavic people by the Romanians, Hungarians, and Austrians in between. The South Slavs today include the nations of Bosniaks, Bulgarians, Croats, Macedonians, Montenegrins, Serbs and Slovenes. They are the main population of the Eastern and Southeastern European countries of Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, Serbia and Slovenia.
The Early Middle Ages in Romania started with the withdrawal of the Roman troops and administration from Dacia province in the 270s. In the next millennium a series of peoples, most of whom only controlled two or three of the nearly ten historical regions that now form Romania, arrived. During this period, society and culture underwent fundamental changes. Town life came to an end in Dacia with the Roman withdrawal, and in Scythia Minor – the other Roman province in the territory of present-day Romania – 400 years later. Fine vessels made on fast potter's wheels disappeared and hand-made pottery became dominant from the 450s. Burial rites changed more than once from cremation to inhumation and vice versa until inhumation became dominant by the end of the 10th century.
The Pannonia Secunda was one of the provinces of the Roman Empire. It was formed in the year 296, during the reign of emperor Diocletian. The capital of the province was Sirmium. Pannonia Secunda included parts of present-day Serbia, Croatia, and Bosnia and Herzegovina.
The Sclaveni or Sklavenoi were early Slavic tribes that raided, invaded and settled the Balkans in the Early Middle Ages and eventually became known as the ethnogenesis of the South Slavs. They were mentioned by early Byzantine chroniclers as barbarians having appeared at the Byzantine borders along with the Antes, another Slavic group. The Sclaveni were differentiated from the Antes and Wends ; however, they were described as kin. Eventually, most South Slavic tribes accepted Byzantine suzerainty, and came under Byzantine cultural influence. The term was widely used as general catch-all term until the emergence of separate tribal names by the 10th century.

The Antes or Antae were an early East Slavic tribal polity which existed in the 6th century lower Danube, on the regions around the Don river and northwestern Black Sea region. They are commonly associated with the archaeological Penkovka culture.
The early Slavs were a diverse group of tribal societies who lived during the Migration Period and Early Middle Ages in Eastern Europe and established the foundations for the Slavic nations through the Slavic states of the High Middle Ages. The first written use of the name "Slavs" dates to the 6th century, when the Slavic tribes inhabited a large portion of Central and Eastern Europe. By that century, nomadic Iranian ethnic groups living on the Eurasian Steppe had been absorbed by the region's Slavic population. Over the next two centuries, the Slavs expanded southwest toward the Balkans and the Alps and northeast towards the Volga River. It's still a matter of controversy where the original habitat of the Slavs was, but scholars believe it was somewhere in Eastern Europe. In the past not much attention was paid to the origin of the Slavic people.
