"Vikings" is primarily a historical drama charting the sagas of legendary Norse figures like Ragnar Lothbrok. While rooted in history and legend, it occasionally ventures into the realm of historical fantasy by incorporating elements of Norse mythology, prophecy, and spiritual experiences.

The series is known for its brutal realism in depicting Viking life, warfare, and exploration. It delves into their culture, religion, and expansionist ambitions as they raid and settle across Europe.

Travis Fimmel's portrayal of Ragnar Lothbrok is particularly magnetic, anchoring the early seasons. While the fantasy elements are less overt than in other shows on this list, the inclusion of seer visions, divine interventions, and interpretations of Norse gods places it on the fringe of the historical fantasy genre, offering a gritty, compelling look at a fascinating historical period with mythological undertones.

"Da Vinci's Demons" presents a highly fictionalized, action-packed account of Leonardo da Vinci's early life. This series imagines the Renaissance genius not just as an artist and inventor, but also as an adventurer, a mystic, and a hero involved in secret societies and quests for forbidden knowledge.

Set in 15th-century Florence, the show blends historical figures and events with fantastical elements, including ancient cults, mysterious texts, and supernatural visions.

It's a visually dynamic series, filled with inventive contraptions (often inspired by Da Vinci's real designs), sword fights, and political intrigue. While not historically accurate, it's an entertaining ride that portrays Da Vinci as a swashbuckling hero navigating a world on the brink of discovery and darkness.

The series is steeped in gothic atmosphere, exploring themes of faith, damnation, and the monstrous within.

Eva Green delivers a spellbinding performance as Vanessa Ives, a mysterious woman at the center of the unfolding supernatural events. It's a show that revels in its period detail and embraces its horror roots, offering a sophisticated and often terrifying look at the battle against forces of darkness, both external and internal. If you enjoy historical settings infused with genuine scares and complex characters, give this a look.

"Merlin" offers a fresh, youthful take on the legendary tales of Camelot and King Arthur. The series reimagines the classic characters, focusing on a young Merlin arriving in Camelot where magic has been outlawed by the stern King Uther Pendragon.

Merlin, blessed with powerful magical abilities he must keep secret, becomes the servant of the arrogant young Prince Arthur. Their evolving friendship forms the heart of the show, as they navigate the politics and dangers of the kingdom, often secretly aided by Merlin's hidden magic.

It balances adventure, humor, and drama, making it accessible to a wide audience. While it takes liberties with the source material, it delivers an engaging story about destiny, friendship, and the struggle between tradition and change. It's a fun entry point into the world of Arthurian legend.

This limited series is a delightful, dryly witty adaptation of Susanna Clarke's acclaimed novel. Set in England during the Napoleonic Wars, it imagines a world where magic once existed but has long since faded, only to be tentatively rediscovered by two very different gentlemen: the reclusive Mr. Norrell and the charismatic Jonathan Strange.

"Jonathan Strange & Mr Norrell" is less about flashy spells and more about the theory, practice, and peculiar nature of magic itself, alongside a deep dive into English history and character.

It captures the unique tone of the book perfectly, blending historical detail with a sense of uncanny wonder and a touch of dark fairy tale. The period detail is exquisite, and the performances are wonderfully understated and eccentric. If you appreciate intricate world-building and a more cerebral approach to fantasy, this is a must-watch.

The show builds a fascinating, detailed world where winged faeries, horned pucks, and other mythical beings navigate prejudice, poverty, and political maneuvering.

Its intricate creature design and elaborate sets create a truly immersive atmosphere. Beyond the mystery, it serves as a compelling allegory for real-world issues of immigration, racism, and social injustice, all wrapped up in a captivating fantasy setting. Orlando Bloom and Cara Delevingne lead a strong cast that brings this unique, atmospheric tale to life.

"Outlander" offers a captivating blend of romance, historical drama, and time-bending fantasy that's truly unique. It tells the story of Claire Randall, a married combat nurse from 1945 who is mysteriously swept back in time to 1743 Scotland.

Suddenly thrust into a dangerous, unfamiliar world, Claire's modern sensibilities clash dramatically with the customs and dangers of the past, particularly as she finds herself falling for Jamie Fraser, a chivalrous young Scottish warrior. The series excels at immersing you in the rich, rugged beauty of the Scottish Highlands and later, other historical periods and locations.

The chemistry between the leads, Caitríona Balfe and Sam Heughan, is off the charts, grounding the fantastical premise in a deeply emotional love story. It's a series that doesn't shy away from the harsh realities of history while still embracing a sense of wonder and adventure tied to its core time-traveling element.
