Creating a timeline in Google Slides is a great way to visually depict events or projects chronologically. Here are the steps to create a timeline in Google Slides:

Step 1: Open a new Google Slides presentation or select an existing one.

Step 2: Click on the Insert dropdown menu and select “Drawing”.

Step 3: In the pop-up window, click on the “New” button.

Step 4: In the drawing canvas, click on the “Shape” tool and select the horizontal line.

Step 5: Draw a line in the canvas to the desired length and thickness.

Step 6: On the right side of the drawing canvas, click on the “Text Box” tool and draw a box below the horizontal line. This will serve as the timeline labels.

Step 7: Add your desired timeline labels in descending order from left to right, starting with the earliest date first.

Step 8: Click on the “Shape” tool again and select the “Arrow” shape.

Step 9: Draw an arrow at the beginning of the horizontal line, pointing to the earliest date on the timeline.

Step 10: Click on the “Arrow” shape again and draw another arrow at the end of the horizontal line, pointing to the most recent date on the timeline.

Step 11: Click on the “Text Box” tool once more and draw another box below the horizontal line. This will serve as the event labels.

Step 12: Add your desired event labels in chronological order beneath their respective timeline dates.

Step 13: Once all labels and arrows are in place, save and exit the drawing canvas.

Step 14: Click on the “Slide” dropdown menu and select “Change background”.

Step 15: Click on the “Choose image” button and select an appropriate image to serve as the background for the timeline.

Step 16: Resize and position the drawing canvas in the center of the slide as desired.

Step 17: Add any additional details or visuals to the slide as needed.
