When Peter Paul Rubens accepted the commission for King James I Uniting England and Scotland in 1632, he was not just painting a monarch—he was visualizing a political dream that had yet to fully materialize. The union of the crowns in 1603, when James VI of Scotland became James I of England, was a momentous event, but the formal political union of the two kingdoms would not come until over a century later, in 1707. Rubens, ever attuned to the power of allegory, was tasked with celebrating the ideal of unity at a time when it was still more aspiration than reality. In the painting, Rubens captures the imagined moment of concord: King James I stands at the center, regal and resolute, as he joins the symbols of England and Scotland—perhaps the Tudor rose and the thistle—into a single, flourishing emblem.

The king’s gesture, extending a hand to unite the two nations, is mirrored by allegorical figures, possibly Peace and Justice, who flank him and reinforce the harmony he seeks. A shaft of golden light bathes the scene, emphasizing the divine sanction often claimed for royal acts. Rubens, with his characteristic dynamism and theatricality, fills the canvas with movement and rich color, a contrast to the more restrained approach seen in Anthony van Dyck’s later royal portraits. The precise medium of King James I Uniting England and Scotland remains uncertain, as does its original location, but it is consistent with Rubens’s grand allegorical commissions for royal patrons across Europe.

While the painting’s early history is not fully documented, it reflects Rubens’s close ties to the English court—he was knighted by Charles I in 1630, just two years before this work. Today, the painting stands as a testament to Rubens’s role as both artist and diplomat, weaving together political ambition and visual spectacle at the height of the Baroque era.
