What Was the First LEGO Set? Unveiling the Origins and Evolution of a Timeless Toy

LEGO has inspired generations through its iconic interlocking bricks and imaginative play. What started as a modest Danish workshop has become one of the most recognized and beloved toy brands in the world. While millions are familiar with the colorful sets of today, many collectors and enthusiasts often ask: what was the first LEGO set?

This article not only uncovers the origins of LEGO and its first official set but also explores the most valuable LEGO sets ever released. Along the way, we’ll highlight LEGO Mystery Boxes – an exciting and innovative way to collect rare LEGO items and elevate your building experience.

The Origins of LEGO: From Wood to Bricks

LEGO’s journey began in 1932 in Billund, Denmark, when Ole Kirk Christiansen founded a company that originally produced wooden toys and household goods. As times grew difficult during the Great Depression, he turned his focus to toy-making.

By 1934, the company adopted the name LEGO, inspired by the Danish phrase “leg godt,” meaning “play well.” The company’s most transformative innovation came in 1949 with the introduction of Automatic Binding Bricks – early versions of what would become the modern LEGO brick.

Though rudimentary in design, these bricks introduced the revolutionary idea of modular, interlocking construction, and in 1958, LEGO finalized its stud-and-tube interlocking system, a design still used today.

What Was the First LEGO Set?

While LEGO began producing individual plastic bricks in 1949, it wasn’t until the early 1950s that it released its first full set: LEGO Set Number 700. This humble box of colorful bricks marked a turning point in toy history. Unlike today's themed kits, Set 700 contained basic pieces in assorted colors and sizes, all designed to promote open-ended, creative construction.

The packaging was simple – a cardboard box featuring hand-drawn illustrations of models that children could build. There were no instruction manuals or characters, just a box of parts and endless possibilities.

Although modest by today’s standards, LEGO Set 700 was a foundational release. It represented a new philosophy in play: one that encouraged creativity, problem-solving, and hands-on learning.

How Early LEGO Sets Differ from Today’s Kits

LEGO’s first set invited users to imagine and invent without limitations. There were no branded franchises, no guided builds, and no digital enhancements. It was pure creative play.

Modern LEGO sets, in contrast, often feature specific themes—Star Wars, Harry Potter, Marvel—and include highly detailed instructions. Builders now follow a narrative or objective, often assembling complex models with thousands of pieces.

The evolution reflects LEGO’s ability to adapt while staying true to its original mission: inspiring creativity.

The Evolution of LEGO Sets Over the Decades

The 1960s and 70s saw the addition of more specialized pieces like wheels, windows and doors, enabling builders to create vehicles and buildings with greater realism. In 1978, LEGO introduced minifigures, giving life and personality to their sets.

By the 1980s and 90s, LEGO had expanded into themed sets like Space, Castle, and Pirates. The launch of LEGO Technic and later Mindstorms opened doors to engineering and robotics. In the 2000s, partnerships with global franchises brought cinematic universes into the world of bricks.

Today, LEGO caters to everyone—from toddlers to adult collectors—with sets ranging from Duplo to complex architectural builds and licensed collector editions.

Why LEGO Collecting Continues to Grow

Focus your collection by theme or series. This gives your collection structure and makes it easier to identify which sets to pursue.

Store sets carefully in a dry, cool environment away from sunlight to preserve color and condition. If possible, keep original packaging and instruction manuals intact.

Explore reliable sources. In addition to LEGO’s official store, some online platforms and specialty retailers often stock rare or retired sets.

Participate in the LEGO community through online forums, local meetups, or fan expos. These are great ways to learn, trade, and discover new collecting opportunities.
