On 21 January 2025, a fire at the Grand Kartal Hotel at the Kartalkaya ski resort in Bolu Province, Turkey, killed at least 78 people, and injured 51 others. The fire started in the hotel's fourth floor kitchen/restaurant section. It occurred during the Turkish winter school break, when the hotel was 80–90% full. The scale of the fire and number of deaths were exacerbated by the absence of smoke detectors, automatic sprinklers, functioning fire alarms, functioning emergency exit lights, and other fire safety measures. Rescue efforts were hampered by freezing weather and the hotel's remote location; firefighters did not arrive until over an hour after the fire was reported. Most victims died from suffocation.

Bithynia (; Koinē Greek: Βιθυνία, romanized: Bithynía) was an ancient region, kingdom and Roman province in the northwest of Asia Minor (present-day Turkey), adjoining the Sea of Marmara, the Bosporus, and the Black Sea.

The Kingdom of Bithynia (Ancient Greek: Βιθυνία) was a Hellenistic kingdom centred in the historical region of Bithynia, which seems to have been established in the fourth century BC. In the midst of the Wars of the Diadochi, Zipoites assumed the title of king (basileus) in 297 BC. His son and successor, Nicomedes I, founded Nicomedia, which soon rose to great prosperity. During his long reign (c. 278 – c. 255 BC), as well as those of his successors, Prusias I (r. c. 228 – 182 BC), Prusias II (r. c. 182 – 149 BC) and Nicomedes II (r. c. 149 – 127 BC), the Kingdom of Bithynia prospered and had a considerable standing and influence among the minor monarchies of Anatolia. But the last king, Nicomedes IV, was unable to maintain himself in power against Mithridates VI of Pontus. After being restored to his throne by the Roman Senate, he bequeathed his kingdom through his will to the Roman republic in 74 BC and it became the province of Bithynia et Pontus in 63 BC.
