Bogleheads, a term intended to honor Vanguard founder and investor advocate John Bogle, are investing enthusiasts who participate in the Bogleheads Forum. The forum's members discuss financial news and theory, while also helping less experienced investors develop their portfolios. There are more than 82,000 registered members and the site receives an average of nearly 2,000 posts each day. Some members also participate in national or local chapter get-togethers.
The Bogleheads community encompasses the forum, the wiki, and three investment books (The Bogleheads’ Guide to Investing, The Bogleheads’ Guide to Retirement Planning and The Bogleheads' Guide to the Three-Fund Portfolio). Affiliated sites include a presence on Facebook and Twitter, The John C. Bogle Center for Financial Literacy, a series of podcasts and a blog.
The Bogleheads approach begins with an investor deciding on percentage allocations to various asset classes, such as U.S. stocks, international stocks, U.S. bonds, etc. The desired allocations are then implemented using low-cost vehicles which are true to the targeted asset classes. Tax costs are carefully considered, influencing decisions as to what investments to place in taxable versus tax-advantaged accounts.
Bogleheads emphasize regular saving, broad diversification, and sticking to one's investment plan regardless of market conditions. Information relevant to the group's core beliefs is available in both The Twelve Pillars of Wisdom and Vanguard's investment philosophy, and are explained in greater detail in Bogleheads investment philosophy.
The Bogleheads' history is one of growth and an increasing sense of group identity.
The Bogleheads group informally began in March 1998 when Morningstar established the Vanguard Diehards Forum to discuss Vanguard funds. By October 2001 the Morningstar forum had grown into Morningstar's most popular forum.
Today is a very special day for Morningstar's Vanguard Diehard Forum. It is the first time any Morningstar Forum has received 100,000 postings. My first Diehard post was in March 1998. None of us ever dreamed that 43 months later we would be Morningstar's most popular forum.

In July 2001 Alex Frakt and Larry Auton debuted diehards.org as a convenient index and search capability in support of the Morningstar Vanguard Diehards Forum.[notes 2]
Figure 1 shows how the diehards.org homepage originally looked in September, 2001.
The Bogleheads Forum
An independent and noncommercial Bogleheads Forum was established on February 19, 2007 by an individual with username Phoenix. The primary driver behind creation of the new forum was acute disruption at Vanguard Diehards resulting from Morningstar's lax moderation policies. Technical obsolescence of the Morningstar boards was a secondary reason. One week after founding, Alex Frakt and Larry Auton agreed to host the new forum. [notes 3] Alex and Larry accomplished the changeover quickly, and the diehards.org homepage adopted a split-screen format, listing posts from both forums.
Figure 2 shows the look of the diehards.org homepage in March, 2007, when it incorporated posts from both Morningstar and the Bogleheads forum.
After the inception of the Bogleheads Forum, activity on Vanguard Diehards decreased markedly, primarily due to rapid growth of the competing board. Also contributing to the decline was Morningstar's unpopular site redesign in September 2007.
On May 31, 2008 Alex and Larry switched default domain names from diehards.org to the more natural bogleheads.org. The newly minted bogleheads.org home page no longer indexed posts from the Vanguard Diehards Forum.[notes 4]
In April 2008, a small group of forum members began experimenting with an off-site wiki. After a few weeks of joint effort, the group presented the forum administrators with a proposal to create a Bogleheads.org. hosted wiki. The forum administrators agreed with the proposal, and Alex and Larry kindly consented to host the new venture. The wiki was officially introduced on May 13, 2008.

The John C. Bogle Center for Financial Literacy
The John C. Bogle Center for Financial Literacy, a non-profit organization set up to help support the forum as one of its stated objectives, was approved by the IRS as a 501(c)(3) public charity on February 6, 2012. The approval was retroactive to Nov. 22, 2010, the date of the organization's incorporation as a non-profit Texas Corporation.[notes 5]

In one of its first actions, the Center trademarked the name "Bogleheads", and it is now a Registered Service Mark of The John C. Bogle Center for Financial Literacy.
